If Ra's Al Ghul is pro-depopulation, why have a child?

[OopsIdiditagain]

Ra's Al Ghul has stated many times he feels the growth of humanity's population is threat to this planet and it's environment. Yet he chooses to contribute to this harm by having kids and grandkid? Wouldn't it be more efficient if Ra adopted anti-natalist values too?

Explanation of anti-natalism:
"Antinatalism, or anti-natalism, is a philosophical position and social movement that assigns a negative value to birth. Antinatalists argue that humans should abstain from procreation because it is morally bad. In scholarly and in literary writings, various ethical foundations have been presented for antinatalism"


Sorry if this came out of nowhere. Ra's reminds of people who preach about others getting steralized or euthanized because "overpopulation is hurting the environment" while also having offsprings and trying to live as long as possible. In short he's a hypocrite.
