Wrong. Talk to him every day. Hang out on some weekends, and become friends. Plant subtle notions of egalitarianism through your friendship and generosity. Ask him thought questions about his beliefs, but not in an accusatory manner. Teach him to actually think for himself, to keep an open mind, to seek evidence rather than faith to form convictions. Slowly show him by example what it means to be a good person who cares for their fellow human beings.

Then you plant some drugs on him while at work, and call HR with your suspicions.
