I too have a roo I raised from day 1 of life, and he can be a pistol. The one thing I encourage you to do is give him every opportunity before you re-home him (a lot of those people just throw them in a pot or use them for other horrible things). Mine was a perfect gentleman until he reached around 20 weeks, then he started jumping on every hen possible, rough and pulling feathers. It was kind of awful to watch but I gave it some time as no one was getting injured other than being p.o.'ed at the loss of their dignity- lol Now the hens just squat when he comes near and he is less interested in bothering every single female every minute of every day. He was more successful with an older hen who treated him as just another bothersome male who she had to ignore except when she was caught for a minute. He comes after me whenever I go into his home zone, because he doesn't want me to hurt his hens. If they aren't around, he doesn't bother me at all- he will even eat out of my hand at times.
Most rooster experts will tell you that they calm down mating-wise, considerably, as they get older. He is now only doing what he is hard-wired to do so I have to think about how he interprets my actions to avoid any issues with aggression- that works almost all of the time. For the rare moments he does see me as an invading monster, I usually wear very thick overalls and boots so I don't even feel him if he pecks or jumps at me. A blow to his ego but it makes me feel very comfortable. I know what you mean about those moments of "hate" when you first experience roo aggression but calming down, ignoring them if they come after you, staying away from their hens if they are feeling territorial which is usually outside, and remembering his behaviors are absolutely nothing personal against you or the hens- it is what being a true flock protector and umpteen years of biology to mate that keeps him going.
People who tell you to separate are absolutely right. These guys can start to get attacked by the hens if they are crossing a line and they can really damage him. I spent much time talking to a life-long owner and researcher of roos; he said roosters do not NEED hens any more than hens need roosters. Putting them in a different coop or area can make everyone's life more bearable (caveat- if you plan on putting them together again as he calms down, do not leave him so far away that the hens don't see him every day). As previously said by someone else, there can be some real reintroduction problems.
My roo is a large Black Copper Marans. He dwarfs everyone else but he has been torn apart more than once by the hens. I am now giving him one more chance with the older hen who ignores him but, if that isn't successful, he will be a confirmed bachelor for the rest of his life!
