Once you submit to blind belief as a person and as a society, there is no limit to stopping these things.. in the name of unseen. You may find these ideas of evil spirits and supernatural ghosts, outrageous.. but almost all religious persons believe in some sort of un-scientific and unproven faith concepts.. an unproven without evidence belief/faith may lead people to do and justify any immoral thing they would otherwise find very wrong.
