Now this is getting a biiiit too disturbing to be fun IMO. O_o Reminds me of that stabbing session in the first Scream movie, where the bad guys are trying to get away with murder by making it look like they get stabbed themselves, but take it one step too far... feels like: this is one step too far. I'm thinking with harm on a more superficial level (blunt objects that seriously injure but don't cause massive bloodshed and death), or without dialog; more 'intent to kill' it'd work better. Good buddies brutally killing each other maybe-not-intentionally-but-with-known-probability is just eh... not my cup of comedy.
