For people who project, are they aware they are projecting?

My brother is basically an abuser. He's done everything from laughing when my grandma died, stealing money from people, punching, throwing things, threatening with knives/objects, saying how he wants to become a serial killer, putting people at risk, I mean everything. And then he turns around, and says how other people are bad or evil. So I'm just wondering, does he realize that he's the bad one, or does he truly believe in his twisted mind that he's alright, and everyone else is to blame?
