He went through mixed emotions throughout the series, and was clearly searching for his own identity from season 2 on.
Jane, it could be argued, was just as bad for him as he for her. A perfect storm of sorts. He had nothing to do with Brock and wanted to kill Heisenberg (as he was at that point) for what he had done.
I get what you're saying, that trouble followed him -- that he gravitated to it -- but it's what made his story more compelling for me. The way he struggled with himself and those around him, his trust in the wrong people, a very polarizing and well developed character whom I had the utmost sympathy for.
