JOKER is as realistic as they come. Reminding me of some form
of PHANTOM OF THE OPERA. A character crossed or rejected
from society. That feels the need to let go and tell the world
of the crime against them and needing a
personal act of vengeance to get the point across.
A character of CHAOS as real as some form of JACK THE RIPPER.
Now if this isn't a form of boogeyman than what is.
