So many complete ignorant fools throw the word 'satanic' about, without even knowing what it means and why it was demonised by patriarchy. Like mind controlled minions they just listen to the perverted preachers at Church and continue to spread their lies. Calling anyone who is a psychopath 'satanic' because of the fact that they are stupid enough to believe Satan is some kind of beast with a forked tail that psychopaths worship and sacrifice babies to. The masses need to grow up and quit being so deluded.
Psychopaths are psychopaths because of issues with how their brain works, not because they worship some imaginary devil. We are not in the dark ages now. Some people are just bad through and through, they don't care about anyone but themselves. Deal with this fact instead of trying to imagine it is something humans are not capable of. 666 is the number of the Beast, the beast is man, this is why Aleister Crowley called himself the beast, he knew this.
