Every human has a right to life.
Every human has a right to procreate.
It is the height of hubris, and I will say that it is evil, for me to say that I can tell another human that they have no right to live, or that they have no right to procreate (e.g., because of some vision I have of a future potential society that may or may not ever exist). It is far better to let them try and fail than it is for me to impose my will over their will, and never give them the chance to live or procreate at all. I would never do that. And, I would oppose anyone who tried to do that to me, or anyone else.
There are natural harms, and there are human evils. Natural harms exist without us doing anything. You lament that, and I understand that lamentation, and join with you. But creating a human evil in response to a natural harm only makes things worse. It is better for individuals to freely compete against the natural harms, and try to overcome them, than it is for humans to impose human evils on other humans. Natural harms just are. Aggressions (by one human against another) are just wrong.
