I am not aware of any specific war crimes he participated in. I mistakenly gave him the benefit of the doubt and assumed he had grown from the kind of uncritical person who joins the military, hence leaving it and running on anti-imperialist policy.

It’s not unreasonable to see a guy who comes away from the military saying “Hey this is bad and we shouldn’t do it” and be easily led to believe the guy saw what he was a part of and understood it needs to be stopped. Every successful revolution includes former soldiers of the regime who’ve realized they were on the wrong side.
