Your instincts or "chemical reactions" are just loving telling you to reproduce because they want you to pass on your genes.
Why would you care to bring life that will hog up your money anyways? If reincarnation is real you won't even be related to them anymore, right?
When you die you won't care about their future accomplishments because you'll be dead.
you do know that like biologically everything is suppose to reproduce
Humans evolved to the point where they can now choose to reproduce.
