Famously when Moshe came down from Sinai the first time and saw the Jews sinning he cast down the tablets of the law given to him by God. My question works on the basic assumption that these tablets were not given to Moshe personally, but that he was in fact working as an agent to accept them on behalf of the Jewish people as a whole. I do not have a source for this assumption but it stands to reason as it is clear that the second set of tablets were given to the Jewish people as a whole and kept in the ark (along with the first set).
My question then is if the tablets were not Moshe's to break, was he guilty of stealing or otherwise causing a loss to the Jewish people for breaking them?
I realize there is a statement in the Gemarah where cause affirms Moshe's choice to break the tablets, but I don't believe that bears on this discussion as that gemarah is not speaking from a legal perspective.
