I just realized an ambivalence in the first sentence. What I mean to say is that dying is an option that only a stupid person would actually choose. I do not mean that everyone below a certain threshold should die and prefer if simple no one dies. Ever.
Terminal values and preferences are not rational or irrational. They simply are your preferences. I want a pizza. If I get a pizza, that won't make me consent to get shot. I still want a pizza. There are a virtually infinite number of me that DO have a pizza. I still want a pizza. The pizza from a certain point of view won't exist, and neither will I, by the time I get to eat some of it. I still want a pizza, damn it.
Of course, if you think all of that is irrational, then by all means don't order the pizza. More for me."
