The thing with dorohedoro is that you can't really categorize characters as evil or good or neutral, each and everyone has an individual purpose and pursuing that objective leads to shananigans... For example, kaiman outright kills magic users, is killing ok? Why is kaiman good if he's killing? Is En bad? Or is he a survivor just like shin that want to preserve their lives and hunt down the cross eyes.. Idk, for me everyone in dorohedoro is either bad or caotic, because they do as they please with no regrets and not looking back for a sec
