Yeah can imagine it would be hard to film such gory scenes for someone like Ryan who's nothing like his murderous character in here.

Yes Ryan does not seem anything like his character in this movie. Makes it hard yet fun to play.

Indeed it would have been a really fun challenging role for him to play

Do you see him doing anything like this again in the future?

Maybe, I won't totally rule that out especially if he does like the script of the movie he gets to play a villain in.
