Is it normal that i hate my brother passionately?

I'm the oldest of six children and I get along with all of my siblings except for one brother. This one particular brother is a thorn in my side. He eats all the food in the house, sleeps in until 2 pm some days and smokes everyone's cigarettes. he always expects people to do things for him but won't lift a finger for anyone else other than himself. He smokes all my weed and never shouts back. It's even worse on my payday, he follows me around like a bad smell asking for money and shit but come his pay day you don't see him until he's spent all his cash. He's a deadset retard. He says and does the most dumbest shit and thinks he's being funny. Most people I know think he's a useless sack of shit. I've punched his face in more times than you could imagine yet he never learns his lesson. I'm quite embarrassed to admit that I'm related to him. Just thinking about him makes me want to push him off a cliff!
