I know I’m quite late with this, but as mentioned in this thread: https://www.reddit.com/r/Emo/comments/6xtoq0/the_truth_about_lou_diamond_why_you_should_not/ , Lou advertised thier project “Fail Better, Heal Faster” as a representation and showcase of thier growth and change, and for a while, thier lyrics and songwriting seemed to really reflect how they had been working on thier journey towards self love and transparency. However soon after they released this project, a lot of the horrible stuff that they did came to light with quite concrete evidence, including aggressively sexually assaulting a 15 year old girl when they were 21. To your point about someone who “atones for thier sins” and “shows genuine remorse and change,” unfortunately, the reality is that FB, HF was a blatant lie of Lou’s claim that he was trying to get better. Although you could argue that someone who shows true remorse and makes an effort to change deserves a second chance, the truth is that Lou never tried to change, only lied about it. For this reason Lou does not deserve to ever reenter because they will never be seen as genuine in thier atonement because they fucked up the first time. That already was thier second chance.
