But if you're asking if a person should be able to choose to die if they wish, I'd say "yes, in theory". By which I mean, everyone gets to decide if life is worth it to them, but the question doesn't effect only the individual.

It effects other people too, and if it effects them enough, they deserve some input to your decision.

This is another way of saying that the decision to end your life should be a rational one. And even then, it should not be entirely a selfish one. You alone get to decide for example if a physical condition causes you so much suffering that your life isn't worth living. But part of that decision is still how it impacts others.

Interestingly this cuts both ways. My previous / late wife wanted / needed to let go and allow herself to die, and understood how that would effect me. But she asked me for permission to go. If I had not given it, she would have hung on a little longer but it would have been selfish on my part to not set her free.

Most suicides are irrational or short-sighted or selfish or driven by depression or other fixable or transient things. But a few are not. Society's failure to understand the difference has forced some people to suffer a lot more than they should have to.
