'God doesn't play dice' ---said Albert Einstin in full confidence.He was speaking metaphorically about the order found in the universe and nature.But quantum mechanics proved him wrong.This might be the reason why it is impossible to combaine general relativity with quantum mechanics. Unpredictable and complete random behavior is not rare: life, human behavior etc for example.Einstin was an amazing scientist and human being.He was nontheless falliable at many levels and ways.So I can't take his words as sacrosanct.
