I'm all for the systemic approach, which means putting the boundaries inside the limitations of the rules: you should be free to ATTEMPT to kill anyone. Which doesn't mean you are also entitle to the right of having a fair chance to succeed.
I'd be perfectly fine with certain fights being virtually impossible for the players and their parties.
Yup. +1. Allowing players to do anything, doesn't mean everything should be doable, even if game is rigged to continue either way just in case.
