Found this on Reddit:

Walter did not ruin everything it was Jesse.

Jesse has become many people favorite character and I can get that. However, Mike was wrong about what he said to Walt last night. It wasnt Walt who ruined everything. It was Jesse.
Walt was actually enjoying himself at first working under Gus. He had a great lab, a good smart partner in Gale.
Jesse was the catalyst for the shit storm. He threatened to rat on Walt from his hospital bed. Forcing Walt to get him to replace Gale. In turn, Jesse being the screw up that he was, stole from Gus, nearly got himself killed going after the street guys. Walt saved his life.
Sometimes it seems even the writers just throw this out the window and ignore that it happened. And I do like Jesse but it kills me how he has miraculously become smart and level headed suddenly and how he escapes a lot of the blame when he should shoulder most of it.
