One thing I've learned, their personalities are as varied as people. It doesn't even really matter what breed or how nice a Rooster's dad is either, you never know what you're gonna get. I've been blessed, raised 11 Roosters with love, various breeds, & 10 are lovebugs to this day. 1 "can" be a lovebug once he's on my lap.
2 other Roosters came my way already grown, treated them with love as well, but they never quite became Lovey, although they will gently take treats from me.
So the Roos that are just as loving & snuggly as can be with me, & they don't care for strangers but they just keep distance, no aggressive behavior at all towards humans.
My very 1st Roo, Rocky, raised him with love & he did get a lot of attention as he & his hen were the only 2 chicks in the beginning. He got quite ornery & spurred me a few times before I started picking him up immediately upon entering his space & carting him around under 1 arm, as I did the chores I needed to do 1 handed. I still have him, he has calmed down considerably as he's matured & he responds to me talking to him, saying hello Rocky & telling him I'm coming in to clean, etc. He mostly just watched me & even let me pet him, in fact, even in his grumpy 1st year of life, he still enjoyed lap time being fussed over, once I got ahold of him...go figure. He dislikes any strangers though & will chase & spur a stranger if they enter his space, particularly men. I have large predator proof pens though, so it's not like I have to worry about anyone running around my yard...that would be a totally different scenario I believe.
1 Roo, a rescue of a young cockerel dropped off, was never mean, just afriad. He likes treats but otherwise just avoids human contact. When I do have to catch him, to do a check over for health, mites, etc. he screams at 1st, poor dude, I have calm him down in a soothing voice & tell him it's OK, just checking you over buddy.
The only truly mean Roo I had, I got him at 6 mos. old. The 1st year he just avoided me. The 2nd year, suddenly he started attacking me.

Who the heck knows why! I tried to continue to treat him kindly, but he started becoming aggressive. When he jumped up & kicked me in the face, leaving a puncture an inch from my eye, I decided a year of his being mean to me for no reason, was enough, & I rehomed him.
So, unless you've got the predator proof pens & can decide to put up with possible attitude & specific procedures prior to entering that section, I'd recommend rehoming or removing the trouble maker.
Another thing those trouble makers do...it's not just about their attitude, but also the attitudes of their hens responding to him. Hens get nervous, flighty & not so calm & sweet, & they can even take to pecking hard at you collecting the eggs, or other Roosters learning bad habits just from seeing him be a jerk. Once I removed Mr. Trouble, Everyone else calmed down & became significantly sweeter!
Best of luck with whatever you decide.
