I don't think it true that people are violent in nature. I think it is the opposite, people are good in nature but they just forgot about it. People become violent if they are depress, disappointed and angry or provoked. They don't know how to manage those things and somewhat, they resort into violence and rage. Factors also influence man's behavior towards himself and the environment and yes, the exposure of the person in a bad/unfavorable and unhealthy environment imposes him to act the same way as others do. Education is also a factor because it teaches us to be refined, civilized and not to act as if we are barbarians.
in my opinion. people or a person become violent only if they were provoked by somebody or any situations... i know that every person has its own goodness and badness..
I think everyone has the capacity for violence. Some have better control over it than others. For some its simply a matter of exerting some self discipline, but there are those that arent equipped with those controls, because of mental illness and other conditions like dementia and autism.
