Did you see the camera? There's a bunch of dudes with AK-47s and a long range photography lens poking out of a corner. I'm sorry but they aren't inhuman, they were eager to shoot because an RPG has killed a lot of soldiers, they also mistook the camera for an RPG on the ground. They didn't see that they had kids either.

The war is fucked, but it's not our place to judge imo.
