you'll learn. Our rooster can be a real jerk. He became aggressive toward humans at about 11 months. After a few episodes of me grabbing him by the tail feathers and picking him up, then calmly petting him and holding him for about ten minutes, he eventually learned he cannot win. He's become a much better behaved boy. People who kick their roosters or force them to the ground only make them more aggressive in my opinion. When bringing treats like raisins, offer them to him first and let him distribute them to the hens. It's often our behavior that triggers theirs.
