I would usually stay out of this as well, but for some reason I feel like responding.
First, let me express my condolences. Having been treated in such a way myself, it is understandable that you would feel such anger. It really hurts to be treated sub-human.
But remember this: if you seek revenge (especially if you stoop to his level), your brother will only use that as justification for treating you that way. You may feel a momentary rush, but it will make the problem worse. If he is not going to be mature and considerate of you, you must be for yourself. Although he does such things without provocation, do not allow yourself to get sucked into the trap of wronging yourself by providing him with fuel for his fire, so to speak.
Your brother's life is his, and it sounds like he is wasting it. In doing so, he hurts you. But the biggest risk here is not the hurt he causes you, but the temptation you might succumb to by allowing yourself to respond to him as he responds to you, which is something you find unacceptable. When we do what we find unacceptable, we violate ourselves and it extracts a high price. We slowly become something we do not want to be.
It may be hard to see it, but underneath your brother's poor actions is pain. Certainly, it is at least partially pain that he is causing himself, and it will certainly catch up with him. There is a part of him, I am absolutely certain, that feels bad about what he does to you. So, in his mind, he has to "villainize" you to justify to himself in doing what he is doing. He will do this plenty on his own, but he will be hypervigilant to find anything you do that would act as justification.
You cannot control him. You have tried, and it sounds like the more you try, the worse he gets (as is often the case). I believe that part of your solution will be to give up trying to control him. It is amazing to me how often, when we give up trying to change and control other people, they can become less obnoxious and harmful because they feel a decreased need to assert their autonomy against us.
So, while what he does is not your fault, the mature question you need to ask yourself is, "Is there any way, even a small way, in which I am contributing to this problem?" You do not cause his abuse, to be sure, but all you can control here is yourself. Find out what you contribute, and you find out the real realm in which you have power to try to prevent it.
Outside of that realm, what you can do is set up boundaries. Fill your life with other things, and find safe places you can be. As your parents for their help in providing you with times and spaces where you will have some repreive. Find people who are supportive and positive, and spend time with them. Find things you enjoy doing, and spend time doing them. Find things that bring meaning to your life, and spend time doing them. Find things you can do and ways of being that make you feel good about the kind of person you are being, and do them.
