Who's Worse? A Serial Killer or Someone Who Has Children?

Who's worse? The serial killer, or the person who has children? The serial killer is a monster and they know it, viewing fully-fleshed people as nothing more than objects to use for their pleasure and destroy. The serial killer puts someone under immense suffering for sometimes days and then kills them, ending their life. No doubt the serial killer is a heinous monster who should be brought to justice, caring not one bit about the feelings of others.
  But what about the one who has children? They end up being a monster without realizing it. They forcefully create a being that's aware of it's suffering and for years they get to brutalize their own creation and expect it to do things for them. The innocent being forced to suffer is forced to partake in society and go to school and be forced to study even though in the end it'll all be for nothing as, saints be praised, everyone will be dead and the sun will burn out. To escape the monster known as nature the being lives in neighborhoods were there was once wildlife and instead of predators in the wild there are human predators, such as serial killers. Indeed if people would have children for a logical reason, there would be no people who'd grow up forced to have a stupid job they hate and have to get married and learn all the ways to hate someone they have to live with and, yes, end up getting victimized by a serial killer. Luckily for serial killers, humans grow on trees, thanks to mankind's own foolishness. In fact while the suffering a serial killer inflicts upon their victim is immense, it's nothing compared to decades of suffering brought upon by their spouses and family and coworkers and society and children and getting old and withering away and dying.
  So, who do you think is worse?
