Before I Turned Evil!!

HE THEN RAISED THE KNIFE, STICKED THE BLADE IN HIS MOUTH AND THEN WITH A SUDDEN THRUST, SCRATCHED IT FROM BOTH THE ENDS AND DARK RED BLOOD STARTED SPREADING ALL OVER THE FLOOR!!
It's about...
How the Joker became the Joker!
How the worst became the worst!
How the evil actually became the evil!!
And...
What's behind the man with Mask?
What's behind his ever laughing Face?
And what pain does he hide behind his Smile??
We all want to know...
"This is the Story of the Unknown Victim but the well known Villain!!"
How really the Victim of the Story turned into the Villain of the Story...
