For real, walt broke more than bad. He went straight to hell and didnt come back up. I guess the moral of the story is that anybody can become that way when given the circumstances and conditions. Regardless, he was not an honorable man. He was a monster that did some horrific shyt for his ego, greed and etc. In fact, he might be worse than marlo. At least marlo was what he was and knew it. Walt literally was teaching kids in class after killing people. And at the very end, he did all that shyt for nothing and left his family worse off.
