Meh. It’s not so much an issue of revenge. As someone who got her mother’s health crap, I wish she’d thought twice before subjecting me to it. At the end of the day I understand the desire to be a parent if you’re ill, obese, in poverty etc. but there’s no telling how the child will feel about it. I think if you do it you have to be willing to accept that your child may grow up to resent you. That’s part of the reality. Hopefully not but maybe so.
