It's normal but hate is a strong word. You might not like him and have a strong dislike for him but you probably still love him at the same time. Think, if he died how sad would you be? There's a difference between not wanting him to have been born and wanting him to die...and I doubt you want him to die. You're going through your "get annoyed easily" faze. It's hard, I know. And he's going through his "annoy everyone" faze. As you two get older you'll get along more. Brothers and sisters are supposed to fight but at the same time they're always there for you. I'm 19 with a younger brother. Good luck!
I know siblings make you miserable , I know! But in the end family is all you have bro , trust me when you guys are grown up, you will love each other to death , just love on him man but him things take care of him put him first treat others as you would wanted to be treated , not how you are treated , trust me I've been there done that
It's totally normal, I hate my brother too. Sometimes I just hate him but there are these moments when I just want him to die, but i love my brother and you love your brother (well i hope so :p) Just enjoy every moment you can with your brother before it's too late. He'll get mature but he's your brother so you'll have to live with it. ;)
You don't hate him if you feel bad about it
