So I have a party member who is a recently minted Witch Hunter. He has played the role very well, keeping his identity mostly secret and relying on it only when necessary. His first official duty was to arrest and execute a known murderer who the Party actually knew and had a grudge with. He carried it out in great RP fashion, trying to take pleasure in it but ultimately being revolted by the excessive violence required.
As time has gone on, he's settled into the role and I haven't really challenged him yet with a nice moral dilemma. I am not an expert on the WH world, so I wanted to see if you guys could provide a few possible situations I could put him in that would test his moral compass vs. his loyalty to the Temple. My first thought would be him encountering a practicing, unsanctioned female using magic to heal soldiers. His duty would require that he arrest and/or kill her yet he's the type of character that would hesitate to punish someone for doing something noble like healing people.
