What about the father?
I assume you’re talking about the deeply personal decision to kill a baby, rather than the deeply personal decision to poison a husband.
The father of a baby has NO legally-recognized existence when it comes to killing his baby.
BTW: As long as abortion is legal, I support the abolition of compulsory child-support. I also support the abolition of compulsory child-support except when the father of the child and the mother of the child were married at the time of the child’s conception.
