That’s the wall the Russian royal family was executed in front of. Those are bullet holes in the photo. Two of the Romanovs were underage children at 13 and 17 years of age when they were executed by the communists. In hexbear world this is fine because they may have hypothetically formed a counter revolution against the communists if they were allowed to live. They’re not wrong that this may have happened, they’re just dickheads for rationalizing why it’s ok to murder children.
