Ultimately, evil will be brought down. At some point, the Second Coming of Christ will appear which will be the final answer. But there can be interim judgements along the way. Corrupt empires have fallen before. The Old Testament shows over and over the dealings of God with evil.
Psalm 37:1 Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity.
2 For they shall soon be cut down like the grass, and wither as the green herb.
3 Trust in the Lord, and do good; so shalt thou dwell in the land, and verily thou shalt be fed.
4 Delight thyself also in the Lord: and he shall give thee the desires of thine heart.
5 Commit thy way unto the Lord; trust also in him; and he shall bring it to pass.
6 And he shall bring forth thy righteousness as the light, and thy judgment as the noonday.
7 Rest in the Lord, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.
8 Cease from anger, and forsake wrath: fret not thyself in any wise to do evil.
9 For evildoers shall be cut off: but those that wait upon the Lord, they shall inherit the earth.
10 For yet a little while, and the wicked shall not be: yea, thou shalt diligently consider his place, and it shall not be.
11 But the meek shall inherit the earth; and shall delight themselves in the abundance of peace.
12 The wicked plotteth against the just, and gnasheth upon him with his teeth.
13 The Lord shall laugh at him: for he seeth that his day is coming.
14 The wicked have drawn out the sword, and have bent their bow, to cast down the poor and needy, and to slay such as be of upright conversation.
15 Their sword shall enter into their own heart, and their bows shall be broken.
16 A little that a righteous man hath is better than the riches of many wicked.
17 For the arms of the wicked shall be broken: but the Lord upholdeth the righteous.
18 The Lord knoweth the days of the upright: and their inheritance shall be for ever.
19 They shall not be ashamed in the evil time: and in the days of famine they shall be satisfied.
20 But the wicked shall perish, and the enemies of the Lord shall be as the fat of lambs: they shall consume; into smoke shall they consume away.
21 The wicked borroweth, and payeth not again: but the righteous sheweth mercy, and giveth.
22 For such as be blessed of him shall inherit the earth; and they that be cursed of him shall be cut off.
23 The steps of a good man are ordered by the Lord: and he delighteth in his way.
24 Though he fall, he shall not be utterly cast down: for the Lord upholdeth him with his hand.
25 I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging bread.
26 He is ever merciful, and lendeth; and his seed is blessed.
27 Depart from evil, and do good; and dwell for evermore.
28 For the Lord loveth judgment, and forsaketh not his saints; they are preserved for ever: but the seed of the wicked shall be cut off.
29 The righteous shall inherit the land, and dwell therein for ever.
30 The mouth of the righteous speaketh wisdom, and his tongue talketh of judgment.
31 The law of his God is in his heart; none of his steps shall slide.
32 The wicked watcheth the righteous, and seeketh to slay him.
33 The Lord will not leave him in his hand, nor condemn him when he is judged.
34 Wait on the Lord, and keep his way, and he shall exalt thee to inherit the land: when the wicked are cut off, thou shalt see it.
35 I have seen the wicked in great power, and spreading himself like a green bay tree.
36 Yet he passed away, and, lo, he was not: yea, I sought him, but he could not be found.
37 Mark the perfect man, and behold the upright: for the end of that man is peace.
38 But the transgressors shall be destroyed together: the end of the wicked shall be cut off.
39 But the salvation of the righteous is of the Lord: he is their strength in the time of trouble.
40 And the Lord shall help them, and deliver them: he shall deliver them from the wicked, and save them, because they trust in him.
Revelation 18:1 And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory.
2 And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.
3 For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies.
4 And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
5 For her sins have reached unto heaven, and God hath remembered her iniquities.
6 Reward her even as she rewarded you, and double unto her double according to her works: in the cup which she hath filled fill to her double.
7 How much she hath glorified herself, and lived deliciously, so much torment and sorrow give her: for she saith in her heart, I sit a queen, and am no widow, and shall see no sorrow.
8 Therefore shall her plagues come in one day, death, and mourning, and famine; and she shall be utterly burned with fire: for strong is the Lord God who judgeth her.
9 And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning,
10 Standing afar off for the fear of her torment, saying, Alas, alas that great city Babylon, that mighty city! for in one hour is thy judgment come.
11 And the merchants of the earth shall weep and mourn over her; for no man buyeth their merchandise any more:
12 The merchandise of gold, and silver, and precious stones, and of pearls, and fine linen, and purple, and silk, and scarlet, and all thyine wood, and all manner vessels of ivory, and all manner vessels of most precious wood, and of brass, and iron, and marble,
13 And cinnamon, and odours, and ointments, and frankincense, and wine, and oil, and fine flour, and wheat, and beasts, and sheep, and horses, and chariots, and slaves, and souls of men.
14 And the fruits that thy soul lusted after are departed from thee, and all things which were dainty and goodly are departed from thee, and thou shalt find them no more at all.
15 The merchants of these things, which were made rich by her, shall stand afar off for the fear of her torment, weeping and wailing,
16 And saying, Alas, alas that great city, that was clothed in fine linen, and purple, and scarlet, and decked with gold, and precious stones, and pearls!
17 For in one hour so great riches is come to nought. And every shipmaster, and all the company in ships, and sailors, and as many as trade by sea, stood afar off,
18 And cried when they saw the smoke of her burning, saying, What city is like unto this great city!
19 And they cast dust on their heads, and cried, weeping and wailing, saying, Alas, alas that great city, wherein were made rich all that had ships in the sea by reason of her costliness! for in one hour is she made desolate.
20 Rejoice over her, thou heaven, and ye holy apostles and prophets; for God hath avenged you on her.
21 And a mighty angel took up a stone like a great millstone, and cast it into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all.
22 And the voice of harpers, and musicians, and of pipers, and trumpeters, shall be heard no more at all in thee; and no craftsman, of whatsoever craft he be, shall be found any more in thee; and the sound of a millstone shall be heard no more at all in thee;
23 And the light of a candle shall shine no more at all in thee; and the voice of the bridegroom and of the bride shall be heard no more at all in thee: for thy merchants were the great men of the earth; for by thy sorceries were all nations deceived.
24 And in her was found the blood of prophets, and of saints, and of all that were slain upon the earth.
