A subreddit centered on the phenomenon of mass murder and the perpetrators who commit them, their motivations, crimes and the psychology of these individuals.

This subreddit is not meant to glorify mass killers, but rather to discuss and attempt to understand their behavior.

A mass killer is defined as one person who kills 3 or more individuals arbitrarily in a contained population at a single point in time. This includes mass shooters, bombers, terrorists, and family annihilators.

Notice: This subreddit is not actively monitored, so the posts here are only a small subset of what exists on reddit.
