To be somewhat fair to Walt, he wasn’t doing it only for himself, the point was to make money for his family so when he’s gone they have a better life.

No, Walt was doing it for himself. The first attempt at cooking and the shit-show with Crazy 8 I can accept as a terrible mistake, but he was given a blank check by Elliott and Gretchen which he turned down because he felt powerful making drugs. The whole point of the show is watching a prideful, narcissistic man bring entirely avoidable ruin on himself, his family, and everyone around him.
