The Passover of the Bible where the blood of a slaughtered lamb was meant to pacify the Lord when he passed by at Midnight so he wouldn’t kill the firstborn of the household is comparable to the tradition of dressing up in costume for Halloween.
Halloween costumes are supposed to ward off evil spirits so they won’t do you any harm. The gorier, uglier and scarier the costumes are the better effective they are at keeping evil spirits away. Gory, ugly and scary costumes work based on the idea of what evil spirits look like. The costumes look akin to the evil spirits.
With the idea of evil comes grotesque, unnatural and death. Halloween costumes depict the image of evil, evil in its natural state, raw and unmasked. If the idea of evil being thwarted is by wearing scary costumes what would wearing cute, friendly, sexy and playful costumes do?
If evil bypasses evil then cute costumes won’t do anything. They won’t be effective. It would seemingly make the wearer stand out to passing, wandering evil spirits. The evil spirits would see the cute features of the costume and be drawn, attracted, to them as opposed to a person not wearing a costume.
A person not dressing up for Halloween would be safer than a person wearing a costume and would have the same chance of being attacked by a menacing evil spirit as among others without a costume.
Evil spirits can notice scary costumes to since anyone wearing a costume will automatically stand out.
If you don’t want to fend off an evil spirit you might want to make your own costume so that you can put extra gore, ugly and scary into it. Some of the costumes that stores carry are more kid friendly. The costumes lean toward being cute and safe so that smaller kids won’t be frightened as bad. If you are going to put yuck in a costume you may want to go to places where there won’t be any small kids.
If you don’t want to fend off an evil spirit try to stay away from those in cute costumes. Remember that evil spirits are attracted to cute and if one should happen to go after someone in a cute costume the spirit might decide to go after you to. If you are around a cute costume and catch wind of an evil spirit heading your way pretend that you are going after the person in the cute costume to throw the spirit off your scent.
