A number of them were either wounded and alive but too weak to move, or actively playing dead. He knew this and wanted to make sure they stayed down. It wasn't a berserker frenzy, just cold murder.Ugh, some of the video clips made me legitimately sick(er than typical videos of people being shot). When he started emptying bullets into already dead people, especially that one woman, I couldn't stomach it anymore. The unecessary violence is shocking.
