It's debatable could Sentinel betray Autobots since he technically was an Autobot Leader.
He didn't have to switch sides and become a full Decepticon to still betray the Autobots.
He betrayed all that he originally stood for and believed in as a Prime, all that was symbolic to the very nature of being an Autobot: That all life is sacred and should be preserved at all costs.
In essence, he betrayed his own teachings, ideals, and ethical standards.
It's like if George Washington, after serving his term as President, suddenly plotted to attack other nations on behalf of the United States, in hopes to expand the U.S. territory by conquest, believing it to be a glorious and just cause, when such methods would be the exact opposite of all that he accomplished to help make the U.S. what it had become, and would turn Washington into a hypocrite and traitor to all that he had stood for.
