Oh anger

Anger is a one of the most influential emotion in this world I guess. It always happened in news, in stories that how powerful anger is. For example we always can find in news that teenagers killing and as a cause of anger. Well, it seems like younger people have less control on emotions.  

We are always saying "Anger is evil". It is evil like demon. Because it leads people away from coolness  and do something crazy even out of control. For example killing in an accident. But in an another way anger will increase one's power, "wake him up". It always happened in the examples in battles. Commenders are always trying to wake up the soliders' anger. It is the large side. In a small side, I had experiences about when teenagers fight with each other. Anger may make others feel scared, or the angry people is hard to face or figure out. I may say anger is a kind of weapon, a "double-edged blade". It all depends on how you use it.
