I think Baburam is well aware that crimes have been committed not just by the army but also by his cadres; possibly himself too while issuing orders. This in itself could be a big motivation. But, I kind of sympathize with him when he says we can't get stuck in the past and have to move ahead. Scratching the old wounds will never let us advance. This is why I agreed with your point that this should apply to everything else, not just the maoists side of things.
I think it's about time we draw a line how far back we want to look at things. The "people's war" has created huge issues between army-people-maoist and for all the sides to move ahead, we have to stop picking every hurt wound. For the ones affected, it is easier said than done and I understand that; but let's get out of the past now and march forth.
