OK, let me address that specifically, Volomon.
Is death possible. Yes.
Should the GM kill my character "because he feels I, the player, have committed an act that is terminally stupid"? No.
If I end up dead because I failed my dodge roll, my damage resist roll, my stabilization roll, and my healing roll, AND chose not to burn all remaining edge to stay alive, that's fine, that's on me.
But dying because you, the GM, ALLOWED my character to jump out of a 40-th floor window when I, the player, misheard you or misread the description and thought I was on the 4th floor, to me that's just dick move.
