While we may not know the real number, there were many people who died as a result of the revelations of Jonathan Pollard, it is the main reason, I suspect, the US has refused to release him. I don't know of anyone dying because of Snowden's revelations, and Snowden hasn't, as far as we know, received money, and it appears his actions were not based on monetary again, so don't try to make some false equivalency between Pollard's actions and Snowden's. Pollard didn't do it for Israel, he did it for the crudest reason of all, monetary compensation. He was trying to sell intelligence to anyone willing to buy.
