First of all, we define it as a form of activity between behavior and performance art. Killing Matt is not just a group, it has changed from a family to a social state and a way of life. The cultural way to kill Matt is a cottage school that combines European and American rock and Japanese visual education. He has been in the concept of cosplay and visual system. For the killing matt that appears on the internet now. Whether it's the visual system or cosplay. Only he can understand the meaning. But most people who kill Matt to dress up. The main purpose is to show yourself. There is no real intention or commercial use. This kind of people, their aesthetic level and aesthetic point of view are different from ordinary people, but they are not morbid. Because even the outlook on life and values can be different, let alone aesthetic. Therefore, the "killing the Matt family" that appears on the Internet now is just an activity form that people want to show themselves, and there is no solution or need. I also hope that everyone will treat similar activities with a normal heart.
