None of them?
Dutch and Micah are both evil, especially Micah.
Bill was never really able to see sense and was incredibly insecure, desperate to prove himself and get revenge on the people who made him feel bad when really that was a him problem. His gang's actions in RDR 1 show that he became deranged and nihilistic, much like Dutch, and as such I'd call him evil too, albeit eventually.
I can forgive Javier's actions in 1899 as he did try to stay neutral. In RDR 1 though, he works for Allende, is presumably an ally of Bill, and overall seems to be a shadow of his former self - having failed to even seek redemption and an embodiment of decadence.
