Answer:
JONAH
Chapter 4, verses 10 and 11:
But the LORD said, "You have been concerned about this vine, though you did not tend it or make it grow. It sprang up overnight and died overnight. But Nineveh has more than a hundred and twenty thousand people who cannot tell their right hand from their left, and many cattle as well. Should I not be concerned about that great city?"
Jonah was a prophet in Israel. Nineveh was an incredibly evil city, not a part of Israel. Their evil became so great that God was about to remove them from the earth, for the good of everyone. Jonah was sent by God to warn them in advance, and provide a chance to repent and avoid disaster. Jonah would rather see them destroyed. Before you think that this is an example of vindictiveness on the part of God and his people, stop and consider that Nineveh was a major threat to Israel, and consider that they were absolutely ruthless with their captives, including skinning them alive. Would you have gone to warn them, or would you hope for their destruction? Also consider that the most vindictive character in this story has more in common with you and me than he does with God. Jonah finally goes to warn the Ninevites, then leaves the city, and sits on a hill under a tree to watch it's destruction from the front row. When the people repent, and the destruction does not occur, he is incensed. Jonah 4:10-11 is God's final response to Jonah's bad attitude. Note that if the destruction of the people didn't matter to him, at least the horrendous waste of good cattle might soften him. You can't say the Bible lacks irony.
