That his former chemistry teacher has been playing him like a fiddle and poisoned what might as well be his adopted son? The fuck is wrong with you nigga?

If Walt hadn't been in the picture dude would just be that skeezy white dude at the liquor store reeking of meth smoke and depression.

Dude was never Walt's partner, he was a pawn, and I don't see how you blame him for wanting revenge. Walt is a selfish piece of shit, point blank and period. Excellent character, but I hope Jesse puts a Bullet in his head, and then salts his fucking grave so nothing will ever grow there.
