Help Me Identify This Science Fiction Story

What story is this? I read it a long time ago. Maybe Harlan Ellison. It's told from the POV of a kid who's been abducted by aliens, and they're studying him in order to decide how to deal with humanity, and this kid is just a terror, and he gleefully crushes bugs and stuff like that, and the aliens, who are radically different from us, don't understand the concept of childhood and assume that this kid is representative of the entire human race, and at the end the aliens undertake the extermination of humanity, and the kid realizes that he's really screwed up.
