I agree, humans come first. And you aren't going to reform this rooster.
Tell your husband that you do NOT want chicks from this rooster. Aggressive behavior has a strong genetic component, so you will be breeding this behavior into your flock. If you hatch chicks from this boy, you'll have to watch your back around your rooster forever.
Roosters are extremely easy to come by. I give away roosters routinely, and am thrilled to do so, as the alternative is often to cull them. When raising roosters, many of us subscribe to a very strict policy--show any aggression at all, and you are GONE. That's because we don't want to perpetuate those aggressive genes in our flocks, as well as the fact that we want to enjoy our birds, not watch our backs. And there is nothing that shows that human-aggressive roosters are any better at protecting their flocks than non-human-aggressive roosters.
You're ahead of most people who come to BYC with a problem rooster because you already have people who want him (although I'd be a little nervous about such enthusiasm--is there a lot of cockfighting near you?). As for a new boy, look on Craigslist, look on the Buy-Sell-Trade forum here at BYC, and you'll find a new boy. You can find even purebred roosters free and cheap almost any time of year. Heck, I gave away a cockerel to a guy I met in
TSC this past spring who wanted a rooster. Then be prepared to get rid of any boy that shows aggression towards you or the hens and try again.
Every single day, so many good, non-aggressive roosters are killed simply because people can't keep them. Instead of giving a home to a proven aggressor, save one of the non-violent boys whose only crime is being born male.
