I’d imagine deaths are non-canon, otherwise we probably would’ve gotten some indication by this point. If everyone is unaware then it’d just be a kinda pointless addition.
This ain’t Madness Combat where the only way for a character to actually die is for them to be wiped out by godly lightning that destroys the entire mortal plane.
People die, it’s what they do, the player is built different because they are in a video game.
