... he gave Jesse the money. The money Jesse launched everywhere.

Jesse seemed fine cooling out with Brock and what's-her-name without the millions of blood money and Walt in his life. Walt making an appearance after all that time apart on his front door with bags of money set Jesse off on his guilt trip. If Walt simply leaves Jesse alone, none of this happens.

Or if Saul had simply let Jesse get high before the vacuum salesman picked him up. Jesse may have simply vanished. Saul fucked that up.

Or if Hank had not tailed Jesse to Walt's house that day. Hank talked Jesse into going with him during Jesse's meth bender. Jesse didn't roll up to Hank's house as a volunteer.

Or if Walt had not poisoned Brock, and found some other plan... because he must have known that if Jesse found out that Walt fucked with a kid, Jesse's numero uno pet peeve, that anything, and I mean ANYTHING, could happen.

Or if Walt had simply not called those Nazis to meet him in the desert. Hank would still be alive then. Why couldn't Walt be man enough to try to finish Jesse off himself?

Or if or if or if, etc.

It simply can't be laid at Jesse's feet.
