You could work on taming him and gaining his trust. There's lots of methods on this forum for that.
Talking to him, making eye contact in a friendly manner, getting him to sit on your lap until he's calm and able to sit there unrestrained, then making sure you repeat the exercise if he leaps off your lap in flight rather than calmly at the end of the exercise, hand-feeding, etc can all help a lot. Really they're all the average chook, male or female, needs. Some people advise not handfeeding roosters but we've always done that and never had aggression issues. The most important factor there is not breeding human-aggressive animals, not really what you do to them.
Many chooks, especially young roosters, are too afraid and/or respectful of people to be comfortable around them.
Some people prefer them afraid as they think it keeps them safer, but a good rooster is safe whether he's tame or terrified, and a bad one is unsafe whether he's tame or terrified. I've had multiples of both sorts, both tame and wild, traumatized and trusting. I've never found fear to be something you can trust to keep you safe from your own animals, whereas trust is far safer.
He may be just human-averse, some chooks are... Nothing can be done about that, except sometimes life threatening injuries or illnesses that they're nursed through can change their minds about people.
He may be too nervous to be a flock rooster. It's amazing how disruptive and detrimental one spacky animal can be to the rest of the flock's trust of humans. Nervousness can be based on genetics or health and can change for the better or worse but if he's been nervous since infancy onwards, best to assume he's not coming out the other side of the woods, and he's a dud.
A scared or untrusting rooster can train hens to avoid you and think of you as a predator, by making predator alarm noises when he sees you. Even tame hens can come to trust his warnings over their past experience with you, and when he calls them away from you every time you approach, they can learn to just avoid you, and even become afraid of you without you doing anything to engender such fear.
If you just don't feel comfortable about him, best to rehome or cull him. Generally you'll have a feeling about the bad ones before they even show you their true natures, in my experience. Sometimes it's as simple as a misfit situation, where the human and animal in question are both fine but do not connect well and will be better off with others.
If you're sort of on guard, semi-expecting an attack, or just don't trust him, it may be all on your end and he may be picking up on the vibes so to speak and that could be making him nervous. Many animals can't trust humans that don't trust them but of course you'd have to be daft to go around trusting every animal you meet. Fine line to tread. The smarter and nicer-natured the animal, the more likely they are to tolerate your faults or forgive your failings. Stupid or unpleasant-natured animals won't tolerate anything short of perfection on your part, and they can take offense over such subtle and minor things as clumsy body language... Like you approaching their vague, general location, with your body directly facing forward, and failing to stop and turn to the 'away' side somewhat after they've taken fright at your approach. Worst cases of that I've seen had the rooster over 20 feet away, still taking the human's forward walking as a threat and panicking over it. Many people don't even realize such a thing can set a bad trend going between them and a chicken, a snowballing misunderstanding, and many chickens aren't smart enough to observe what a busy human looks like and realize it's not a personal attack. Different people get different results from the same animal in many cases, but a thoroughly good-natured animal will put up with all manner of abuse (intentional or otherwise) and clumsy communication without taking it personally and responding badly.
If he struggles with all his might when caught, I'd be less tolerant of him due to that, it's not a good sign if he's pitting his entire strength against you.
If you restrain his wings so he doesn't feel imbalanced or unsafe, he should settle, but the bird that does not settle not only doesn't trust you, it actively dislikes you. If he absolutely will not accept being handled, that's an issue that generally means future issues are coming and they'll be worse.
It's one thing to avoid you or struggle when caught, but entirely another to refuse to have anything to do with you and battle with everything they've got to be free of your touch. Such animals are more trouble than they're worth in my opinion. Sooner or later you need to treat them or handle them for whatever reason, or their offspring (mentalities are quite heritable), and their mentality makes what should be a simple job either difficult, or dangerous, or downright impossible, and the animals are the ones that have their lives at stake there.
A chook that cannot be handled is a liability both to you and itself. It's for their own good that livestock are kept tame; it's also for our own good. You hear some sad stories about chickens too aggressive or afraid to receive the treatment they need, which then die during attempted treatment for curable issues, because they are too combative or terrified for it to be feasible. There's quite a few threads on this forum where people are suffering emotionally over trying to treat a rooster or hen that is too aggressive or afraid for it to work. Breeding human-hating chickens is asking for a world of trouble. If he were mine, I'd try to tame him, but he'd better respond quickly, or he'd be on the cull list. My experience has been that it's no use trying to work against a mind that is solidly set against you.
Best wishes and good luck.
