When I watched Breaking Bad I was hoping the whole time Walter would give it all up. His students were absolutely perfectly portrayed.
You knew the whole time Jesse couldn't and wouldn't ever figure out what was good for himself...and Walter abused his relationship with Jesse knowing that the whole time.
Walter self-destructed himself and his family. Eventually they were complicit in his self destruction because they liked the money and the model of who he used to be.
Nobody held the high moral ground in the show...even Hank had issues. He kept covering up for his wife's kleptomania.
The prices everyone paid for their behaviors and attitudes were too high. Nobody got away clean. You hope for the best out of people and they usually let themselves down. People usually shoot themselves in the foot. Some use a BB gun and others a 155mm howitzer.
I found the characters completely believable. Do you license poor behavior because "everyone else has moral issues"?
Or do you stick to a different set of rules....ones not commonly held. Or do you fake it like every character in the series? Pretend to be honest but actually lie, cheat, abuse, and steal like everyone else?
