Agressive rooster

[Allyyyyyyyy]

Hi! I have an aggressive rooster names Luna. do you have any advice that I could have to tell him that I am a good person? and I do NOT want him dead.

Not to sound rude or anything, but your attitude is wrong: you don't need to tell him that you're a good person, you need to tell him you're the boss.
Roosters became aggressive when they are cuddled and babied like kittens: they lose all the respect they have for humans and once they hit puberty, they want to dominate everything and everyone.
