Again, Jesse was labeled a snitch. Right? Krazy8 was his source for distribution. Jesse was going to go back to Krazy8 the moment he needed to cook more meth to make money. At which point, Krazy8 would have killed him. Remember, he tells Walt he's "laying low for a while after the bust", but he had every intention of cooking again (It's his only source of income.)
The only reason Jesse didn't die was because he had Walt's bag of meth on him and because he sells out Walter's location in order to save his own skin from the "rat" accusation. When Krazy and his friend show up, they hold guns on Walt and force him to cook, at which point Walt kills them because he knows they are dead otherwise.
So the only reason Walt had this violent confrontation was Jesse's previous relationship with Krazy8 and being labelled a snitch. This is all on Jesse. And regardless of Walt, Jesse dies from this, only Walt's actions save him.
Gustavo, again, Gus was going to kill Walter the moment he had Jesse firmly under his thumb. Walt tried to run, but his money was gone. The only reason Walter, however, COULD be a target fur Gustavo is because Jesse decided to cook for Gustavo, which made Walter expendable. Without Jesse, Walt's not expendable. Not to mention, Walt wouldn't even have ever gotten into a bad situation in the first place because he wouldn't have killed those drug dealers.
So, in this situation 1.) Walt wouldn't have had to fight Gus had he been allowed to cook with Gale. He couldn't because Jesse threatened to rat him out. 2.) Gus couldn't have killed Walt if Jesse wouldn't have agreed to cook for him, because Walt was the only other one who could make the high grade meth. At whichever point you want to go back to--It's on Jesse for making Walt vulnerable and/or instigating the violence.
Seriously, how are you going to say those murders are NOT on Jesse. They clearly are.
