[@deia876lat] He only hates that he did not act sooner because he was a coward and had too much "feelings" i.e wanted friends family etc.  He sees himself as a weapon who only exists. Of course those he sees as evil and last time I checked the Empire is not very good in terms of humanitarian deeds. Does that help? 

He actually sees his casting as a way to connect with his mother who is now part of gia.
