IIRC, he was a successful drug dealer, but wanted to quit, and at the end of the 4th season it seemed it was what would happen. Anyway, as I said before, I enjoyed the last season, but the (more or less) open ending of the 4th wouldn’t have been bad (IMO)
Well, I’d rather would have preferred kind of an “open arch”. To me, during the 4th season, WW was trying to quit and reedem himself ; at the end, it seemed that he woukd be able to. Nevertheless, I enjoyed the 5th season, but… he deserved better (story wise)
Breaking Bad. The whole 5th season seemed unnecessary to me.
I’ve always perceived him as a desperate man that got more and more dehumanized, until, well… found someone truly bad, but not as a bad person himself. But you have a point, he put in such position due to his arrogance.
