Well the two ideas are a Mercenary/bounty hunter so that would fit... the other was that of an Inquisitor, someone who grew up in a church (of random made up religion that is powerful in another land and slightly militaristic) whose thinks his crusade to purge evil is holy and just but in reality he is often the evil doer. That character would be more of a character needing to evolve... anyway I'll see what you got and likely go with the first idea :p
