> Some night even argue that not having kids is selfish.

People argue all kinds of insane things.

Having kids to fulfill your own sense of purpose is very selfish.

On the flip side, there is some probability that your child may save 1 or more lives.

On the flip flip side, there is some chance your child may take 1 or more lives.

Arguing about the selfishness of procreation is silly. It is your biological purpose. Whether you choose to run with that or not is down to you. It is not selfish if you choose whatever way.

As a parent, my children come first. I would die for them. You make that choice when you have children. That is NOT selfish.
