This really does show the way society, no, humans as a whole really are. Those who do not act like the mass are shunned. Those who do not believe what the mass believes, are shunned.
You either act like every other person or you are an outsider. Hated by everyone. To act like everyone else we don't show negative emotion. It brings negative attention. When it comes to the point that you can no longer hide it, you break. Some break away and take their anger out on society, others decide to finally end the cycle for good.
This was a great animation. It really gets you thinking. Thank you very much.
