Does social media bring out the worst in people or are people simply terrible to begin with?

We all have a "dark side"....we all have the capacity and potential to be "mean and nasty" or even just plain "evil", no living person is exempt. However most people also have the ability to control, resist. and even reject such urges so in that sense people are generally "good". There are some who cannot and some even choose not to. The internet is just another means for them to operate with more freedom and anonymity, social media is for them a paradise and playground. It's sad and a shame but it's true.
