Well the OP says 'if' you knew how he'd turn out.
If i didn't know and then he turned out to grow up a non-muslim, i would try my best to convey the message of Islam to him/her. If they fail at accepting it then i can't force my beliefs on him/her.
Why did you answered "other"? I understood you wouldn´t want to have the child? That would be a "no".
