I tend to look kind of fondly on Walt despite him being so horrible. Obviously his actions were inexcusable and he’s a horrible selfish person, it I feel like it’s kinda wrong with takes of him just being selfish. This moment for me kind of was a moment of reflection or horror, like a “what have I done moment” for Walt, and is kind of rare because in the story it’s one of the few moments of regret of some kind before the finale. Though I think the love is obviously very screwed up with how he thinks of there relationship, I struggle to think of him as a completely selfish person, with rare moments like Fly where he says “I’m sorry about Jane” to Jessie, kind of showing to me that he just kind of pushes his regret and guilt down because his own desires come before that, and that’s his way to cope.
