As far as neige, why does it matter when he realized he did wrong? The main thing is that he did. He was never heard being publicly racist, and has clearly distanced himself from the band and their ideology.

Yes. And that makes him a free man who has paid his dues to society. His ex-wife is still heavily traumatized to this day and he has a stage, a band, a label, and a platform.

But Neige was in the band for 8 years until he was 23. And Lambesis has paid for his crime and done his time in jail.

Not to speak of trying to get your wife killed.

Also, Neige was 15 at the time. That's a totally different thing from methodically raping fans over decades, or being an outspoken racist at 50

Alcest at least have publicly acknowledged that and broken ties.

Also heres my list of characters that I think would make awesome guest characters for MK. [link]
