Jesse is a complete and irredeemable fucking twat of a piece of shit piss sponge that ruined Walter's life.
At every single corner if it had been Walter alone he could have turned the sour situation or avoided it completely. Hell his deal with Gus could have turned him into a hundred millionaire in the span of a few years and a life secured for his family for generations if pinkman didn't force him to fuck it all up.
The ONLY time he was truly an assest was directly in the beginning as a means to distribute but that very quickly feel through as he was a dumbass with no spine and basically read off the IKEA instructions and left you with a pile of wooden shit and refuse. After Walter made contact with Gus he should have cut off all contact just as Gus told him he should.
He is a junkie. He is a dipshit. He is a coward. He is scum and every "good thing" he did shadows in the face of his surmounting failures and downfalls.
the whole show sucked
