Very seriously indeed. People who worship evil powers are not safe to be around, and not just in a magical sense. John Gilbert used to say that Satanists want to imitate Satan and get thrown out of heaven, and they do it by misbehaving in more and more extreme forms until the people they're maltreating finally cut all ties with them. All you can do is make that happen sooner rather than later, so you suffer less harm before the inevitable happens.

Er, what does BICOE mean?
