Good and evil. We are taught very early how to distinguish the two. The good guys wear white, the bad guys black. There is a halo on the good guy. The evil one has horns.  But as we grew older, we gradually learned that not all the bad guys look so bad. Sometimes they’re actually friendly and well dressed, until you really get to know them. The devil doesn’t come with pointy red horns and a stench of brimstone. He comes as as an angel of light, to fulfil every wish you have ever had.
