The problem here is do-gooders imposing child support. The mother has the final choice if the kid is born. With choice goes responsibility. Her getting impregnated is a separate issue. If she was impregnated against her will, she should have filed rape charges.
He had the choice whether to have sex with her and take the risk that she might get pregnant. If he didn’t want to take that risk, he could have kept it in his pants. The child didn’t have a choice.
