My father, who flew combat missions for the Navy in Vietnam and then became a test pilot, told me after the loss of Columbia that if he had had a chance to make that flight and spend 7 days in Earth orbit, even knowing that he'd burn up on reentry, he'd have done it.
One way to see it:
(and potentially) So you have a possibility of a guaranteed exciting life for a death that you anyway will have, but doing something you love, it's not too bad.> It's a profession where you intentionally kill people
Not being an astronaut (or being a test pilot, for that matter). That's the context in which he was speaking.
Your father is a better man than I am.
