I'd argue that Walt never directly murdered someone. I mean, he stood by and let Jane die, and that dude he killed in his basement could be viewed as self defense, and though he's indirectly responsible for the plane crash, he didn't set out to kill those people. I might be forgetting some deaths, but it seems like Gale was killed for purely to save Walt's life and Jesse's life.
Well, to get technical about it, Walt's actually been working himself down the murder spectrum. His first, Crazy 8, was a bonafide first degree murder. Jane was probably a 2nd degree, since it was an intentional failure to act that caused her to die. And the dealers he ran over would probably be voluntary manslaughter, since they were a threat to Jesse, but they weren't in the process of attacking him and Walt could've tried to protect him with non-lethal force (putting a bullet in the skull of a guy you just ran over kind of puts the kibosh on necessity as a defense). Gale's is a difficult one to judge, since you get the same jail time for ordering a murder as committing it, but it had been made clear to him that he would be killed himself if he didn't order the death of a bystander, which is something that doesn't actually happen outside of scripted television*.
Not that any of that matters, really. The other victims had all put themselves into direct conflict with our guys in some way. Gale was a threat to them in a roundabout way, but I'm sure he had no idea why he was being shot. On an emotional level, he registers as collateral damage, and while they've certainly racked up a lot of that, they had never pointed the gun and pulled the trigger before.
*I assume. I mean, Survivor's been on for like 12 years, right? It's probably gotten pretty freaky by now.
