No.

Job, the most blameless and upright person on earth, said that if he had ever rejoiced over his enemy’s misfortune or gloated over his enemy’s trouble (which he hadn’t), then he would deserve to have his crops replaced with briers and stinkweed.

David, a man after God’s own heart, wished that everyone who gloated over his distress would be put to shame and confusion.

Solomon, who was wiser than anyone else ever, said that whoever gloats over disaster will not go unpunished. Even if you want to see bad things happen to your enemies, he says you shouldn’t let your heart rejoice and gloat when they stumble and fall, because then God will disapprove of your attitude and will stop doing bad things to your enemies.

God had Ezekiel tell the Ammonites and the Edomites that because they rejoiced when Israel became desolate, God was going to bring other nations to wipe out the Ammonites and make Edom desolate. And God had Obadiah tell the Edomites that they should not gloat or rejoice over the misfortune and destruction of Judah.

Yes.

The Bible says rejoicing over the misfortune of others is what righteous people do. The righteous see the ruin of the wicked and rejoice, and the innocent mock their foes when they are destroyed. David said the righteous would laugh at Doeg when God killed him. And he said the righteous will be glad when they are rewarded by getting to dip their feet in the blood of the wicked.

David, who always behaved just the way God wanted him to, praised God for the death of Nabal. David wished for his enemies to be taken by surprise and ruined, in which case he would rejoice and delight in their downfall. He said God would let him gloat over anyone who slandered David.

And Solomon portrays Wisdom herself as laughing and mocking when disaster overtakes fools and distress and trouble overwhelm them. So that must be a wise thing to do.
