People are quick to blame "human nature" and overlook the role that the system itself plays in the actions of people.
People, generally speaking, are not basically evil. We would never had come this far as a species if that were the case.
I didn't mean that human beings were born evil. I'm just saying that you're always going to have people who will try to do evil things, specifically because we humans (hence, human nature) possess complex minds that are able to premeditate such acts and if there's any way that such acts can be committed with exploitation of freedoms or without a consequence, you would see a more prevalent concept of evil than there is today.
I've seen it, I've seen the destruction it causes to the people involved. Anarchy is what awaits if we get rid of punishment and deterrents. Because that's just the way it is.
