I am very fortunate that I am currently living in an era of peace, without the pain of war. In a war, human nature was shown to the extreme. The concentration camps murdered Jews, youth troops, special forces, dead children, civilians, etc., the behavior is really suffocating. Of course, other countries are not much better, and they are also very cruel to the hostile side. It is absolutely impossible to suppress violence with violence. However, I don't think war is good or bad. When one side wins, it is bad for the other; when one loses, it is good for the other.
