[massacre man]

Pact with the devil
It is said that humans who enter into a pact with the Devil himself do so out of desperation and often, in an effort to seek revenge for the death of a loved one. In popular European superstition, the Devil is said to appear in the form of a coachman whose carriage is drawn by black steeds. The Devil offers a potion that provides the strength needed to carry out the revenge, in exchange for the person's soul. The potion is often in the form of a vial, the contents of which are applied to the human skin under the light of a full moon. The transformation into a werewolf will then begin immediately and the human has been completely turned into a werewolf forever
