They came to the other side of the lake, to the country of the Gerasenes. And when he had stepped out of the boat, immediately a man out of the tombs with an unclean spirit met him. He lived among the tombs; and no one could restrain him any more, even with a chain; or he had often been restrained with shackles and chains, but the chains he wrenched apart, and the shackles he broke in pieces; and no one had the strength to subdue him. Night and day among the tombs and on the mountains he was always howling and bruising himself with stones. (Mark 5: 1-5)

This demoniac was probably a Gentile. The Eastern shore of the Sea of Galilee was populated mostly by Greek-speaking Syrians.

According to Luke the man was naked. This is embarrassing to us. It would have been abhorrent to most Jews.

According to all three gospels the man lived in tombs. For the religious this was spiritually unthinkable. Having anything to do with such a man would threaten your own spiritiual integrity.

The man was strong and violent - though the violence seems to have been targeted mostly at himself. But clearly a frightening character.

If anyone would seem to be outside the care of God, certainly it was this man.
