For many love is possession. He just can't see that - which is why its so interesting. That's why i still see him as an anti-hero.
In a weird way, I do too. He doesn't want to kill or have killed anyone "innocent", or anyone at all really. 98% of the people who have died as a result of Walt; most of them have been pieces of shit anyway. Walt still klings-on to the idea of family. He's not willing to hurt anyone for no reason, Gus, on the other hand, was a gangster from start to finish. I'm still rooting for Walt, I hope he makes it.
