Looking for anti-semites who still opposed the holocaust despite their anti-semitism. The idea just fascinates me.

Only example I have is Wilhelm Canaris, who originally came up with the idea of using the Star of David to identify Jews in 1935, but saw war crimes committed by Einsatzgruppen, most notably the burning of 200 Jews inside a synagogue in Bedzin, and in 1941 saved 500 Jews by giving them token Abwehr training to give them papers allowing them to leave Germany.
