Just like you can't put your elbow in your ear, it's impossible to do anything that's actually evil. Because if it was evil, God would prevent you from doing it.

When I first encountered this concept, I thought that maybe it was one of those German philosophers from hundreds of years ago... You know... The ones I never actually studied... But I found out it's actually the plot of a Teenage slasher movie! And the bad guy in the movie Justified everything he was doing by quoting the "You can't put your elbow in your ear" philosophy...

I'm not sure how the movie ended because I don't care for that type of show and so I probably changed the channel... But traditionally, the beautiful girl kills the bad guy using his own knife...
