Personally, I would accept any form of life before I chose not to exist at all, because I view life itself as a blessing.
I understand that this isn't a philosophy that I share with everybody but you should still be respectful of it.
Just how shitty of a life do you need to have to not be worth living? People who spend their lives in prison don't usually kill themselves. You can read stories about people captured as prisoners of war who have no hope that they will ever escape, but they don't attempt to kill themselves. Are they being "asinine"?
