I mean; I cannot speak for anyone else but myself and how I would react; how I'd do it and why.
Just like how it would be a sweeping generalization to say that all "killers" would kill only the unwilling or torture them to death with a blow torch.
Sure there are probably are those catfishing "types" out there.
But if the person is really wanting to die and doesn't care, I think gruesomely dying wouldn't be to much of a bother.
Who knows.
However; most of you probably would want to know the person taking your life a bit before you know, actually going through with it.
But I've a had a few who even wanted the gritty, gorey death. So.
Personally for me; given the legal go ahead, I'd make damn sure I know the person a long while and had a hearty discussion on how, when, why, where, etc before proceeding.
Let's not make sweeping, irrational remarks.
We're not all out here to give you a dirty death.
