In game you could add the "Dishonorable player" to the report sections, and the matchmaking could try to pair them against other dishonorable players, or give them a tag of shame.
No. Don't take your "safe spaces" into a game where you cut off the heads of your enemies. Honor is a relative term and it should always describe the player and not the game. I play honorable, but I don't want a little safe bubble around me. Come on man.
