Tragedy
There's so much tragedy in the world on an everyday basis, some of it by pure accident, but so much of it done intentionally. It's terribly sad how much we humans dehumanize one another on a regular basis.
The headlines are the obvious examples. But in countless other ways, people are treating other people like shit every single day. Sometimes, even when the courts are involved, people continue to dehumanize other people in their lives, sometimes hiding behind a morally weak lawyer or the cowardice of their lies to an outside authority.
