You're not understanding a single thing I've said. I can only conclude it's on purpose.
The couple has sex. They are BOTH responsible for preventing pregnancy. It's so easy to not get pregnant, as I've repeatedly said. But you refuse to accept that. If she conceives, they are BOTH responsible for that new life. If he walks, she should sue him for child support until the child is 18.
You don't like any of those ideas. You want the most innocent human involved to die.
You are not a good person. You're a death cultist.
