well this can only be answered by those that experienced it, proof is difficult to obtain though, and its very profitable to deceive people about a possible afterlife, after all imagine how cheap an army can be that has been told it doesnt really dies, i bet that at certain stages even entire societies, agree with lieing to their children, like the palestinians just to overcome an occupation.

everyone born into this world lives a curse, that he always has limited information about this world and doesnt understand it. this makes good decisions difficult and very random. :-(
