A great many people put all sorts of things that don't exist (ideologies, dreams, wishes) as more important than the suffering and death of real live actual humans who are really here on earth and really alive.
No. They've rationally decided that the quality of a life is more important than simple quantity.
Please realize that, if someone else disagrees with you (even if you don't understand their position), that does not mean that they are crazy. It doesn't even mean that they are wrong.
They're insane.
