A lot of the dumb stuff Jesse does is only because he's disillusioned and treats Walt as a trustworthy father figure, though. Not that it excuses his actions, but considering Walt started all of this he has to take a good chunk of the responsibility for everything that follows.
Gus and Tio are definitely on the kill list. Like...how would they not be. Walt blew up a bomb strategically while both were around to kill them. It does not get any more clear cut than that. You say he "didn't set off the bomb." He did! He waited until Tio was ringing the bell like mad in front of Gus, flipped a switch, and blew them to hell! That was literally the sequence of actions! You have no argument, zero.
Walt didn't directly kill Tyrus. He's partially responsible for his death. His pride about being in control of the operation led to him forcing Jesse to kill Gale which led to Tyrus being exposed to the public which led to Gus killing Tyrus as an example and to keep the operation safe. Walt is partially responsible for Tyrus' death. This is also pretty inarguable.
As for Jane: I won't say that that one's inarguable, though I think it's pretty clear that he again shares some responsibility. You don't blame a junkie for being a junkie. Addiction is a disease. That doesn't mean it's fully malicious, but it was rash and selfish and short-sighted and cowardly. Those aspects of it, at least, are pretty impossible to deny. It's not brave or strong to let a mentally diseased person die in their sleep while you stand over their body.
