That's because some of Jesse's actions are just that, inexcusable.
Look at this.
You remember what lead up to this threat? Jesse chose to STOP the destruction of the RV, stole it (Yes stole, don't forget, it's Walt's RV, he paid for it), and walked right into Hank's trap . He brought this on HIMSELF, and he is here threatening Walt's life (Continued Cook), his family's life (Going after Hank)--everything. Walt doesn't just have him killed, which he UNDOUBTEDLY could at this time, with Gus' men. Instead he puts his reputation on the line to prevent Jesse's idiotic escalation and removes Gale, the ultimate lab assistant, to try and appease Jesse. (Oh and after he does this, Jesse skims Meth which threatens both their lives and sells it to recovering addicts, all because he feels like his millions aren't enough. Nice, Jesse.)
Yeah, stretching bro, okay. If Walt was half the monster you think he is in this relationship, right here, Jesse dies. He isn't. Walt's "manipulations" have consistently been to keep Jessealiveand out of trouble. (And again, even before Walt met Jesse, Jesse was dead. Crazy 8 blamed him for the snitch, it was ONLY Walt's Meth that saved Jesse. That's it, then Walt physically saved Jesse by poisoning and strangling them.)
And lol, he told him "to get fucked"...When the hell was that? Are you talking about the scene where he told him he wanted to help him? And he was scared he would OD? And he didn't want to give him all the money so he could shoot up with it? Is that the scene where he told him "to get fucked"? Or was it only AFTER Jesse once more threatened to destroy everything Walter loved that Walt got angry? (Remember, Walt started the conversation like a father who was concerned for his son, it was only AFTER Jesse's girlfriend threatened him that Walt got mad...And then Walt relented.)
