Thoughts on Walter Jr?

I hated/ignored Walt Jr. so much that it took this post to remind me he is part of the show at all. He's a flat character, a sympathetic sweetheart who is the world's victim. Does he serve any role at all other than as a victim?

The major characters I empathize most with are Skyler and Gus. I like Skyler because she seems like a real human, put into a bind by circumstances and unable to angelically cope. I like Gus because I can relate to how he dislikes drama too close to himself but is willing to go nuclear if necessary to shut it down. I like Mike as a character, but I struggle to relate to his choices.

The minor character I empathize with is Gale. He was probably the peak neurodivergent in the show.
