I'd suggest reading The Abolition of Man by C.S. Lewis for a short but succinct alternative viewpoint. It's not specifically about whether or not to have children, but it talks about what connects the visceral aspect of man with the rational aspect, which is something you seem to be having difficulty reconciling.

But, let's set that aside for a moment. Assuming you believe in evolution and natural selection, you know that every environment has stressors and great filters. With life existing on Earth for 4.5 billion years, do you really want to be the evolutionary dead end of all the ancestors who came before you? In the great dance of life, are you the dodo bird?
