Evil is not optical, it does not exist as a visible thing you can video or create a gif of. There is no horned being in a red body suit to show to the unbeliever. Evil is far more real than what can be touched or put in a jail cell. Indeed, evil is so real you are probably begging it to help you fight all of the bad things that threaten your life and property. What is more, evil is so real it is more than happy to help.
