Diplomacy can't be used against a PC in this manner. It is to resolve negotiations, influence attitudes of NPCs towards PCs (not the reverse...says so in the DMG: "NPCs can never use a Charisma check to influence PC attitudes.") and resolve cases between advocates in a hearing.
I certainly don't think you can use it to convince a PC to do something against his nature.
