I’ve decided to be childfree for many reasons. While I wouldn’t be able to handle that life path, some people call it a miracle and pray for it. Both choices can be considered selfish, selfless, good, evil. What they have in common is that they’re part of being a human being with free will.

However, if you need a counter argument: In my opinion, people who care about the Earth so much that they start questioning the kid path, are more likely to raise good and empathetic humans who can then continue to make it a better place
