I can see your parents were not good to you, but not all parents are bad.
Its not about how the child is treated by parents. What he is saying is that life is inherently a bad thing, as it is mainly suffering with bits of ok moments. He is probably an antinatalist on the humanitarian grounds. Which I am too. You brought a life into this thrasher from non existence, following instinct. And that bred suffering and pain. So philosophically speaking, you've done evil by creating new life.
U followed the instinct or whatever made u have kids. No need to apologise for that, but theoretically he is right
Just because you or I may not be having good lives does not mean that the person you replied to or anyone elses children aren't.
Some people bring children into the world and do everything for them to make sure that they have happy and comfortable lives. And many do that successfully. I struggle to see how that is evil.
Some people deliberately have children they can't look after properly - and sure, I get the argument that is selfish, but with the person you responded to that clearly isn't the case.
Your perspective is primitive beyond belief. He argues for that non existence is inherently and always better than existence.
He also adds that people make kids for selfish reasons. And even care for them for selfish reasons.
So an act of having a child is an act of forcing a new being into suffering,( that is inevitable for living beings,) for selfish reasons.
Yes, that is evil. How good or bad the child's life will be is inconsequential for determining that it is an evil act
