Unlike Jazz, who will remain stunted for the rest of his life, Sander has the ability to change perspectives. Woke is trendy and popular right now but you'd be surprised the emotional and ideological shift that people can undergo in less than five years (Look at how crazy the world has gotten since 2016!). Sander right now is running on a high of social media, validation from his narc mother, and his own lack of wisdom in age. But that changes when you're a lonely man in your 40's with no career, dead parents, no woman who wants to be around your fake personality, and who the fuck even knows about the state of Jazz.
Sander's still a young man. A grown adult, but still a young man. And while I think that his influencer crap and false positivity can get VERY annoying, I don't feel as if any of the kids are deserving of ire. That lies on Jeanette and Greg. None of the kids know they are an enabler of Jazz's abuse. It was not part of the world they lived in and they will not realize this until years from now.
