In the Old Testament, self-mutilation was a common practice among false religions. First Kings 18:24–29 describes a ritual in which those who worshiped the false god Baal slashed themselves with swords and spears, as was their custom. Because of the traditions of pagans, God made a law against this sort of practice. Leviticus 19:28 says, "Do not cut your bodies for the dead or put tattoo marks on yourselves. I am the LORD." In the New Testament, cutting oneself was associated with someone who was possessed by demons (Mark 5:2–5). It was characteristic of behavior caused by evil spirits.
This is horrible and people are mentally ill, possessed or both.
A whole lot of people that I converse with simply do not understand that demon possession does not always take the form of black eyeballs and heads spinning around with pea soup spraying everywhere.
That's the Hollywood version.
Cutting is absolutely a sign of demonic possession, and one that can be easily hidden if the cuts are done in areas that aren't regularly exposed.
