@faraday Here's the problem: Your character isn't the protagonist of the MU*.
It's not.
Neither is anyone else's.
People like to say that they're writing a story, and they are, but they aren't just writing their characters story. They're writing the /Story Of The Game/.
Where your character /fits/ in that story is really going to depend on who's reading it and their take on the story and situation at large.
There is no one single 'Protagonist' in a MU*, at least not on any one I've ever been to unless it was a super FC like Rand Al'Thor on a WoT game. There is no reason /not/ to kill off a character if the games story has lead to that event happening. It all further pushes the story further, what ripples occur because of that death? How does it impact other characters? How does it impact the power structure of the game? How does it alter the future of the game and further the /games/ story?
This is why the idea of immortal characters, that anyone is writing out the 'protagonist' story is a false assumption. Everyone can't be the protagonist. Even if you allow only one specific thing, like only Arthurian Knights, who is the Protagonist? Arthur, Galahad, Gawaine, Merlin, or Lancelot?
It just doesn't work, and when people realize that the games story isn't about /them/, then we can see some beautiful history take place as the game takes on a life of it's own that isn't full of consent abuse and drama llama's.
Just my opinion.
