Warning - this post doesn’t contain specific spoilers, but I would recommend against reading it if you haven’t watched Breaking Bad because it may color your opinions of the ahow

I feel like you missed the point of the show if you thought the point was to show Walter sympathetically or as the good guy. The whole point of the show is that it is his pride and greed are ultimately what drive him to do worse and worse things no matter how much he tries to blame his actions on external circumstances. There are multiple instances where he does things that are completely unnecessary because at his core, Walter White is a bad person. He is not truly driven by desparation or by love of his family, but by his pride. He wants to earn his own money, and he enjoys being above the law and feels that he deserves all his money and power because he is smarter and superior to everyone. As he gets deeper and deeper into crime, it becomes clearer and clearer that his moral decay is entirely his own doing and not primarily driven by circumstances, even though Walter certainly tries to act that way. I can provide specific examples but I wanted to keep this post spoiler free.
