From what we currently know The Beast is formed from shadows which is why that substance around it((the shadows)) is similair to the Oni who also come from the shadows.

Parish stopping the Beast is most likely due to the damage it will do to the supernatural world by exposing it to everyone, that and the thing from what we know currently just lives to kill.
