Walt has yet to kill any innocent people he's only killed to defend himself . You guys find any reason to hate on Walt .
Yeah, Walt only kills drug dealers he voluntarily gets into deals with when they threaten to kill him or his family.
There was also that time he killed two of Gus' men when they were about to kill Jessie, who was pissed that they killed one of his friends after Walt tried to take over some territory.
Oh yeah, he had Jessie kill Gale. Gale didnt' do anything wrong to him, he just had to die so the drug lord Walt voluntarily worked for wouldn't kill him.
So just drug dealers he enter, forgot one more. He almost killed a little kid, just to trick Jessie into joining his side. Kid didn't die though, almost did, but that doesn't count.
So just drug dealers he makes drugs for, the two guys that were about to kill his friend, his assistant that he had killed, and the little kid that ALMOST died because Walt poisoned him.
Walt only kills people when they're a danger to him and his family. But there's no danger though, so Skylar wanting to move her kids away is just her being a bytch.
