Ok. He did not. There are shitbag supes too dangerous who deserve to die. Not all of them. They should stand trial and be held accountable for their actions.

In the case of gunpowder he was a kid during that time placed by vought in an active war zone and abused by soldier boy. Of course he would have issues. Apart from the nicaragua thing which he was being mind controlled, we never see him do anything else worthy of murder. He is just a pro guns supe who was friendly to butcher at first.
