Krampus, The Christmas Devil

I've seen the newly released movie "Krampus." It's good up until the last quarter of it when it gets too crazy for me. Then it ends well, something I should have guessed. But think about how cruel parents were in earlier days not too distant in the past. Not only did children have the threat of Santa reading their minds and not giving them any gifts, or worse, a black coal in their stockings, each culture had a different gruesome threat beyond that, powerful evil creatures who would punish and torture children if they were naughty. The most feared and widely believed evil creature was Krampus, the Christmas devil. He's caught on camera here. ;-) But seriously. Wasn't the threat of a devil and an eternal conscious torment in hell enough? Makes me wonder how these beliefs didn't make thoroughly dysfunctional adults when they grew up.
