Did you know that temperament is an inherited trait? And that this male probably inherited his tendency to human aggression and that he will pass it on to most of his sons? When you are fighting genetics, you are fighting a losing battle. This goes for side sprigs on a comb, crooked toes, red bleed through color, but it just as much applies to temperament.
This is from my personal experience over the years: You can try everything in the book and if it's in his DNA to be this way, he will not change. You may make him afraid of you, but then, he will only become sneakier and attack when you are least expecting it. I've also found that the least intelligent males are the most aggressive ones, in general. The ones who bite (or flog) the hands that feed them are the ones who are not very bright and not prone to learning affection or even basic respecty. ALL my birds are handled as chicks, except the rare one that a broody tries to keep from me. Even then, we do make the attempt to get them used to being handled and inspected. When the males get to breeding age, I begin to back off and give them their space. It's time for them to step up to the plate and protect the flock, but a rooster should never protect the flock from his human caretakers (unless they are abusive, of course, but that's another situation). He must be intelligent enough to understand who is the enemy and who isn't. Some just don't have the brain cells to do that. I've had a rare couple that just could not learn that we were not the enemy, however, they were a rare exception because I keep only non-human aggressive males and breed from them. That has served us well in producing well-tempered roosters over the years. The mean ones don't get to propagate here.
*in all this, I'm speaking of the large fowl roosters who can do some damage if they attack you. The tiny Belgian D'Anver bantam males are generally known for their aggression. I've also seen they are generally pretty dumb. I do, however, have one friendly one and I've had one semi-friendly son of his as well*
By all means, try whatever you can, but do not be surprised if nothing works. He is probably not capable of changing his behavior, not in any real way.
