Magick has no stance on good or evil, it is neutral. It's the wielder that controls the intent of that power. Magick is both unequivocally beautiful and absolutely devastating, and it comes with every shade of gray as well.
There are some people who suggest that every person is capable of some psychic ability, that it all depends on the amount of activity in your brain. One main theory is that as the average person uses approximately ten percent or less of their brain, perhaps those who access more of that are privy to another "sense," this being psychic ability(ies) perhaps.

Also much of Christianity and its traditions bear root origins in ancient Paganism, take Ireland for instance. In the early to mid eighteenth century the Christian Church was intimidated and bothered by the out-lasting bonds the people of that land had held in Paganism. Thus they began to adopt and mask many customs, holidays, and traditions. Take for instance Samhain (October 31), the ancient Celtic festival intended for remembrance of ancestors and the dead. The church declared the date as All Saint's Day, teaching that it was now a day that God permitted those departed souls to return to their decedents the eve before All Souls Day in order to remind them of their obligations to the dead.
