I do believe there r some truly evil ppl who walk among us. They spread their corruption in order to gain more followers n power. They would enjoy the adenraline rush of killing someone and causing mayhem to Society. The seed of the demon is in all of us, it is how we manage to control n surpress it tht is up to us. Tht is y God's greatest gift n curse is our own freel will. The ability to make our own choices.
