Judging from many of the comments here and in other threads, it seems like no document is actually making people see how terrible these people are. Not even here of all places, where one could assume a decent capacity for rational thought. They either don't want to see the violence, or cannot see it, or condone or even support it. Which doesn't make rational sense, since it only leads to more violence, which I doubt can seriously be the end goal, to escalate us into extinction.

You don't even need to bring morals into it or care about anyone else than your own peers. It just doesn't make any sense other than self-harm and a comprehensible yet pointless expression of own pain.
