Nope. I'm judging them for not making any sense. Someone murdered your entire immediate family and tried to kill you when you were child, which obviously says that this person is fucking crazy if they tried to kill a child, you realize that you have magic powers and can protect yourself and what do you do? Well if you're Harry, you DON'T attempt to learn everything you can so that you can be ready at any time that this person could come for you, even though they attack you your first year at school, and you make fun of your friend for actually wanting to learn.

No one said he had to turn into super-angst boy or woobie (which it can be argued that he does. "MY DAD WAS A BULLY. OMG MY LIFE IS OVER.") but he could at least do the logical thing and study once in a while, especially since he has no idea what knowledge he'll actually need to fight this guy if he ever shows up.
