I have a hard time remembering what about the Beast is from the original rules and what is Jason Carl's personal interpretation, in L.A. By Night. He highly personifies the Beast to provide players something definitive to roleplay against that might otherwise have just been an entirely internal struggle.
If you haven't already, I'd recommend watching LA By Night. It's basically the "Critical Role" of VtM, replete with actors playing the characters and extremely high production value. But most importantly, Carl is an excellent storyteller, and I think this one particular tip is the easiest concrete thing to take and apply at your own game.
