Out of curiosity, why not select life? Everybody sins-- why not accept that maybe this sin is more likely and love the children that might be born to you?
It seems more fair to me if I bear the burden of my moral framework, given the proposed determinism.
Of course, this is sophistry; ask about whether two celibate gay men would be allowed a Catholic wedding and the answer will be no because they can't have children, nature of marriage, yadda yadda. Ask whether a man or woman without intact junk can get married and suddenly it's love that is really important.
