@Brent cv,
I think once your fate is sealed you're free to go out with dignity
Case in point:
My fathers best friend shot himself through the chest after learning late he had a brain tumor and less then a year to live. He didn't want to go out a vegetable after 6 brain surgery's that wouldn't work, he wanted people to remember him as him. He even took a more painful route and shot himself in the chest so that he could have an open casket for his family
nothing wrong with that, his time had come
but when we think about traditional suicide I would say it's wrong because it's unnatural
