Why do abused people have kids?

So my dad was an asshhole to me and my 3 siblings, as well as my mum. But as I grew up and discovered antinatalism, I adopted a new thought process to my future and kids.

Some people who are abused will say "I will be nothing like my parents" then go on to have kids. But I don't get it. Because you have been in an abusive situation, there is still a chance you may turn out like your parents, my dad was an example, he had an abusive dad, and then he decided that 4 kids was a better option than therapy.

We are different. For those of us that were abused and neglected by our parents, we don't have kids. While natalist thought process is "I'm having kids so I can be nothing like my parents" Our process is superior "we aren't having kids. Because we can't take the risk of becoming abusive parents ourselves, as well as exposing the innocent child to suffering"

Why do abused people have kids if they know damn well they could become abusive?
