I agree with Apathy. (Both in this specific and in general world view.)
The base acceptability is wether the player is willing to except the entirety of the paradigm, good and bad, opposed to just the benefits.
The WHY and the HOW of a characters development during character generation, in that order, are always the most important questions.
Personal preference tailors a game to individual tastes, so when killing players,
"One to the head, one the heart."
And I doubt there is a ref who has not thought about it.
