Evil is a strange thing. We all have different definitions of it. I think most of us can differentiate between bad deeds and bad people; we all do bad at times, but most of us are fundamentally decent.
I know people who have stolen, people who have cheated on their partners, people who have hit their kids in a moment of anger. I know people who have run red lights or driven whilst over the limit or cheated on their tax returns. You do too. And you probably don't think that makes them 'bad', at least, not if they are mostly kind and honest in the rest of their lives.
But what happens when someone does something so bad, so shocking, that it completely defines them? Something like pretending to have cancer to get money, or murdering their children, or sexual abuse? Can we separate them from the act? Can we say that they did something bad but are not actually evil?
And if the act of evil is so monstrous that we cannot believe a regular person could do it... what then? Because this is where people tend to fall into two camps. Some people - like me - believe there are evil people in the world. I believe Hitler was evil. I believe Martin Bryant was evil. I believe men who kill their families out of revenge are evil. I believe that if you can distinguish right from wrong and perform an act of great horror, then you are evil.
Other people conceptualise it differently. Other people like Lana, for example. It is something we have debated frequently, and do so again here. And we'd love to know your thoughts. So watch and let us know.
