I believe that adults have the right to decide freely whether they want to live or die, and to have that decision respected. The critical – and difficult – part is that word “freely”. Imagine that you have a friend in an abusive relationship. She is so miserable that she openly says she will let her abuser kill her; she has no intention or will to leave him. In that case, the decision to die may be perfectly rational, but it isn’t taken “freely” at all. Another person has destroyed your friend’s ability to value her survival, and rather than leave her to the death she says she accepts, you will maybe feel that she should be forcibly removed from the influence of her abuser before she can be seen as competent to make life-or-death decisions.
