On further note,
I think I cant have children on -principle-.
I feel like I havent answered the question "why do I exist at all". Of course I do, rationally - I understand evolution and basic biology.
But none of these explanations account for the experience a person will have. As a parent you are directly responsible for everything your child experiences, after all, you pushed it into existence.
And do you have control over all the variables? No. Of course not.
I can't shake the feeling that its fundamentally irresponsible. It takes a lot of faith in your environment to do it. A kind of subtle megalomania, seeing as you're also placing faith in your abilities.
..I might be crazy though.
