a daft question
first off how do you tabulate " i shot him because .. "
or other take one life to save another situations
the " problem " of who gets to choose whoes life was more important - is worth debating - but the OP question - is IMHO daft
also there is the situation where NOTHING happens - and conflict is avoided because one side is armed to the teeth
i have personally been there , done that
a vicious brawl with bats , knives and such can be lethal - but what if just drawing a FOBG makes the otherside blink , and bavk down ?
