This wouldn't come up often, but it probably does happen more often than anybody imagines. Sometimes, our characters find themselves in situations where they are forced to submit or they just decide to. Situations where they find themselves at the mercy of their captors either willingly or not. I think it would be cool to have an @trust added that would allow someone to one-shot, one-cut, one-smash your character so that execution scenes could be just that and not so...awkward.
The @trust could have followups signalling the player what they were about to do so there could be no surprises. Maybe its not part of the fully-auto @trust system either.
not sure if this breaks any rp opportunities that might be afforded by a longer death. But if you want a quick, honorable death, this could work, right?
