I don't believe it's right to raise your kid with any belifes, religious or athiest. Perhaps you should raise him without them and when he's of reasonable age tell him your belifes, then let him make his own decision. Freedom of thought should be given to everyone, raise him to make up his own mind, raise him to be independent, make sure he knows the ins and outs of everything.
Live every day as if already dead, that way you're not disappointed when you are.
