"People who will think he's special. People who will convince him not to kill. People who are okay with bad people dying. People that will challenge his worldview and view of himself."

Sounds like Anduin could help you out here. Rowan sounds a bit "there but for the grace of the Light" for Anduin, actually. He has put his body on the line to stop the deaths of innocents, saved the life of a war criminal who nearly killed him. But he's a discipline priest; he is devoted to Light but also Shadow. His aggressive abilities work on an 'atonement' principle where the harm he does is translated into protection and healing of others. But he also understands retribution- especially if I canon update him shortly...

I think they'd get along well!
