Karmapa, I believe, Turbine by using, "human make mistakes," was merely trying to say that it should be of no shock that someone who is a sankarcharya ( I don't even know what the hell this means) committed murder. There are murderers everywhere, and why do we need to just focus on this particular one? Why? Because Sankarcharya is involved??? He is a human first anyway, isn't it? So let's focus on the one committed by army or maoists in rural nepali village, instead.
