I'm in the "eat him" camp, also. He scratched your face. How close was he to your eyes? Read the posts from the people who have gentle roosters that need to go because they live in town where they can't keep them. Check Craigslist. There are good ones out there. I have had to learn to not get too attached to my roosters. I don't name them because it's much easier to get rid of them that way if they get aggressive. All the best to you if you choose to try to "rehab" him.
