"Secondly, it is to remove the ill-feelings that have manifested within. With these ill-feelings, having the intention to injure and kill others is paving the way to your own death. Experts can sense these ill-feelings. So, to be a successful killer, you have to look even more ordinary than ordinary men and women on the outside. Those who have a murderous look and are putting up a cold front are not worth paying attention to. The way I release stress and manage my ill-feelings is different from the others. It depends on your character, whether you are someone cynical or someone living life frivolously. All in all, as long as I am able to release stress, I will make a successful balance. It doesn't matter how designed is the tactic. A designed tactic to release stress allows the killer to be aware of the opponent's flaws. It is the opponent's deadly flaw."
