A kid *wanting* to feed a crocodile is one thing, just like wanting to drive a train or be a policeman with a gun but this kid actually went and did it. He broke into the zoo first. Then he killed animals by bashing their heads in. Then he fed some to the alligator. I don't know what makes a serial killer but something is not right with this kid, that's for sure. Either he has no clue that any of these things he did were wrong, or he does know. Both are equally disturbing.
