>If the people that remain behind are at peace with the decision it doesn't really matter 'what might have been'.

The problem I have with this is that it also justifies murder. As long as the rest of us are cool with it who cares what the murder-ee thinks?

So what? This is unfortunate but in no way implies that a valid response is "might as well just help them instead". That's not better.

Hearing someone even present this sort if argument makes me wish I could turn their lack of empathy back on themselves. How about we have psyche tests and anyone who would so lightly let other people die, are killed themselves?

Somehow I bet you would say that's immoral and outrageous.

The psyche test would be great. That way anyone who wants to die only has to take the test.
