Violence is a normal thing that always belongs in human history! I'm not saying that the human nature is evil, but not every violence is essentially bad. Slavoj Zizek in your book ''Violence'' he's show types of violence and how they are express in differents situations in different lifes, of course with a political view. One thing that I most admired in book is the subject and object violence. The subject is the violence which us saw everyday in news; violence protests, strikes, brutal police force and etc and the more terrible violence, the object: Is just the systemic violence that explore, segregate, and kill the human to maintain the status quo! That means, kill a person could be a ''good'' thing, depended of your motive! And violence is different from society to society! We can't have a unilateral vision that ''violence is 100% bad every time, everywhere'' and vice-verse! Anyway, this is the violence in a political view, but is a daily view as well!
