Why not have Deacon

Why not have Deacon impregnate the woman? Why all of this torture and anguish to get her boyfriend to do the deed? It can't be easy to get hard under those conditions. But ole Deacon would have no problem with that. He was ready and willing. There wasn't anything gentically wrong with him, was there? I though they said his deformity was the result of an accident. So why not have Deacon do a quick 1 minute rape? They get the baby they want and don't have to bother with the torture and what not. They just could kill the boyfriend right there. And, they could do that wedding ceremony for Deacon and girl so it would be morally right.

I don't know, the whole time we saw Deacon about to bust a nut in his pants while the girl's boyfriend obviously wasn't going to do the deed. I said to myself, have Deacon fertilize the seed.
