Pawns

Outright possession is difficult, often even for Demons of high station. So to influence people most spiritual denizens of hell prefer to turn people into Pawns.
Pawns are people whose minds and hearts have been infiltrated by evil. Through a gap in their characters, always related to sin and moral weakness, the person lacks strong Faith necessary to realize they are being used indirectly by infernal parasites who feed them evil desires and inclinations.
Demons love to turn whole communities into Pawns and then set them loose on their enemies, having the stereotypical 'angry townsfolk' take up arms instead of evil spirits doing all the work. 
One demon can 'produce' several dozen Pawns and keep decent track of them. By injecting thoughts and desires into the Pawn the Demon can eventually change their behavior and personality, ultimately becoming the puppets of the Darkness. 
Exorcists, whose powers are designed to pierce spiritual powers, are perfectly suited for spotting and combating Pawns and their Demonic handlers.
