"Better" here just involves the assumptions that pain is worse than not pain, and that human life is intrinsically valuable. I'm fine with making both assumptions -- especially since I've read Timothy Snyder's _Black Earth: the Holocaust as History and Warning_, which explores the thought of the most famous proponent of the mankind-needs-more-Darwinian-selection-pressure alternative. "I disagree with Hitler" isn't exactly compelling evidence for "my opinions are fundamentally subjective."
(I'm also of the opinion that the earth isn't flat, and that both sides of a contradiction can't be true. In those cases, too, I'm comfortable with saying that those who disagree with me are wrong -- and in uninteresting ways, too.)
