It doesn't seem like he did. Early on in the series (the Dove's Emergence arc) he admits that he understands their purpose and doesn't entirely disagree with it. We see that even in the final arc, he aims to disable rather than kill or maim. So he clearly still sympathizes with them, and as a former human he could understand their existence in dealing with generally dangerous Ghouls like Aogiri. He just opposed the people he cared about -- or innocents in general -- being hurt.
