Classic Harem Master. I see that routinely with my free-range flocks. Where you have ample room, those harem master roosters are the ones that provide protection for hens and young. The negatives of the arrangement can be controlled by dispersing locations where they can eat and just hang out (loaf). If area tight, then either only one or get the standard dead head rooster that is nice to all hens.
Damage to eyes by rooster unusual, very. Are you certain eye damage did not occur first, and then rooster attacks hen?
You bring up a good point. My gold lace polish has never shown any aggression toward ANY of my other chickens. One of my birds sprained it's wing and when he noticed the injury at roost time he charged after it like I'd never seen him do before. I swiftly caught the injured chicken and put it in it's own cage to recover. But what I'm getting at is that injuries trigger something in chickens and will turn the nicest of birds into attackers.
