Man he ges on about people who don't need to say sorry saying sorry, then he himself is apologizing when it wasn't really his fault either. Beautiful , I love this arc!
Disappointed that he basically killed himself. And I hope we stop seeing flashbacks for a while now. I think we know most of the characters past in this manga now. (Except for Muzan)
They all had their circumstances that made them choose to become a demon. But most find comfort at the end in the forgiving embrace of their loved ones. I like how the author finds ways to depict a pure form of regret for past deeds at the end in a very touchy way.
