Yeahhhh
I fee like people are taking things too far when it comes to the morality of this show. Because, it is a show. I'm pretty sure if this was real life, like an actual news story - most of these people would not be rooting for Walt. He's a stylized fictional character, who's journey we've been through.
I also believe those that try to justify Walt's actions to make him a hero, are doing so more of out being conditioned by the usual protagonist role/formula in fiction, and aren't doing so because they have deeply rooted psychological problems.
he's not a hero, he's like the literal definition of an anti-hero.
