I appreciate the thought, thanks.
If the kid had the gene for alcoholism or (if they ever find such a gene) a gene for being sociopathic or violent, I'd probably want that fixed too, if it could be done. Why allow my child to have to live with genetics which will force them to commit immoral behavior? That would be tragic. If I could do something to prevent it, I would.
It wouldn't bother me if the kid was born black or jewish though. I wouldn't be willing to shell out for a procedure to rectify that. Although the hypothetical wife would have to answer some questions about that one!
