Hmm, it seems that Marcus' being a serial....beatdown person would cause problems. So I'll just change that character concept all together, and instead just make him someone preaching against the law, yet having to deal with the fact that he does have a sex drive, and dealing with the conflict of, 'should he be immoral and help humanity, or doom humanity to die and do the right thing'? Not QUITE as interesting as the original character concept IMO, but one I think would work better in the setting (and not cause people to leave due to being, 'uncomfortable').
