I have an abusive identical twin, and it makes me hate myself and everyone else

As per the title, my identical twin is abusive. He snaps at the tiniest thing. He screams at people. Often, he'll be physically violent. He's a total, unrepentant asshole. I have my own anger issues, but nowhere near as extreme as him. But since people can't tell the difference between us, our behaviour often gets conflated. Even when people can tell us apart, I still feel as if I'm held accountable. People don't see me as an individual person, they just see me as an extension of him. I fucking despise him, and I despise anyone who thinks I'm anything like him .
