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.
Can't say there's anything helpful to the family with her situation lol, while understandable to seek that sort of thing given the crazy circumstances he had put her in (if nothing else a sense of control) its not "Exactly like Walt had been doing"
Edit: To be clear, Walt obviously went overboard and it was no longer just for the family, he was doing it for his own self worth as well.
