It's interesting to note that you consider having children a selfish choice, because in some cultures, not having children is considered selfish.

Cultural anthropology might have an answer there. I guess that some cultures and traditions view not having kids as selfish because there's a cultural push for preserving society (kids will become workers, help parents, pay taxes, fight in the army, and so on). I consider myself selfish because I've done it to fill my life with something I felt was lacking. I've no rational excuse.

I think both options are selfish.

You don't do it or not do it for humanity, society or whatever random shit you make up.

If both are selfish, then neither is selfish. You conveniently deconstructed the concept of selfishness and I like it a lot.
