bentaxle: Go for it! However, I think that this is one of the most important questions I, or perhaps anyone else, has have ever posted on answerbank. We all think about it, but push it onto the back burner.
If another party aids you, they are subject to criminality, if a person does not wish to continue, why should they not be allowed to 'fall on their sword', or 'Walk out onto the bacony with a revolver' as kathyan says above, it's my body, my life.
(for the record, this question is academic, not pressing :0)
