If it helps the western and Eastern views on reincarnation are different but the Western still believes that your previous life decides how you will live your life, but the Spirit chooses the form it wishes to take before conception to learn a specific truth. Which cycle is repeated until the truth is learned.
I personally can't see what is sick about the Buddist point of view, they're sayiong that if you are a bad person in this life in the next one you could come back disabled, once more it is about learning a lesson.
The universe isn't fair, it has no sympathy for weakness so why wouldn't this be true? We do not live in a benevolent universe we live in one that is out to get us in a thousand different ways, and many people seem devoted to making it worse, If it is true I can't see a damn thing anyone can do to change it, if it isn't true why give a damn. And you wont know until you get there so why worry about it?
