What does Jonah 4:11 mean?

'Shouldn't I care about Nineveh, that huge city with more than a hundred twenty thousand people who can't tell right from wrong, and all their animals too?' Jonah 4:11 - Modern Text Bible

(God explains that his compassion for Nineveh is much greater than Jonah's for the plant. He cares deeply for all those people and even their animals.)
