Try having your brother give the cat a treat when he comes around. So then everytime the cat sees your brother he will associate him with something good – a treat. Once your brother is able to pet the cat without it freaking out you can have him stop giving the the cat treats.
Once an animal hates a person you can’t make them like/love them.
Your brother will just have to avoid the cat its as simple as that.

If you can keep the cat and get rid of the brother. Cats are a really good judge of people. Sounds like the brother’s gotta go. lol.
ur brother should be friendly with it and have to show his affection on it…then u may see some difference…
