ANYONE dying in the Souls world automatically become Undead. Undead cannot be killed, but they can lose their minds and go Hollow. So technically death doesn't exist? But wait, Gravelord Nito is like, Death, right? So he just got lazy somewhen?
So the only thing that keeps me apart from almost every twichy little guy I have killed is my ability to keep it together and not go Hollow?
Also, dying is also part of the lore, right? I have always see my toon as the bringer of death and destruction; bosses should crap their pants at my presence because they know their days are numbered. They kill me, I return from death ever stronger: "Hey Smough, ain't that the guy we flatten every other day? He seems to have a bigger sword this time around..."
Man, that's like the only thing that keeps me going in the game. Every time I return I brought a bigger stick of pure evil and vengeance!
