I recently watch Steven Pinker's video on violence and figured out that I don't understand the difference between violence and aggression.According to Wikipedia aggression is:Aggression, in its broadest sense, is behavior, or a disposition,       that is forceful, hostile or attacking.and for Violence they use the WHO's definition:the intentional use of physical force or power, threatened or actual,   against oneself, another person, or against a group or community,   which either results in or has a high likelihood of resulting in injury,   death, psychological harm, maldevelopment, or deprivationAt first sight it seemed that the difference could be intentionality, i.e., aggression has intentionality attached to it and violence doesn't.But the WHO's report linked says:The definition used by the WHO associates intentionality with the committing of the act itself, irrespective of the outcome it producesSo the difference is not all that clear to me.
From a psychosocial standpoint, how is violence different from aggression?
