Hold on there, you're overlooking something. The narrative portrays the person as a villain so far, but stories often lead us in one direction at first and then turn things around to surprise us. Characters who seem to be villains can turn out to be well-intentioned extremists, or to be working toward some positive goal that requires harsh methods to bring it about. I'm not saying I believe that's the case here, but just in general, it's dangerous to assume that what a narrative has led us to believe up to this point represents the final truth of the narrative. Stories often mislead their audiences intentionally.
