Batman The Murderer

Batman took Aunt Harriet to the Batcave where nobody could hear her shout.
She learned that Bruce Wayne is Batman and she was rubbed out.
When Bruce asked Dick Grayson to kill Harriet, he screamed "I can't!"
But Bruce threatened to cut him out of his will and Dick killed his aunt. 
Bruce Wayne wanted her dead and he didn't care that it was vile.
Dick killed Harriet when he dumped her inside of the Atomic Pile.
She learned Bruce and Dick's secret when she discovered the Batpoles.
It didn't bother Bruce one bit to see Harriet die because he's an asshole.
Dick committed murder because he didn't want to be cut out of Bruce's will.
Don't try to expose Bruce Wayne's secret because if you do, you'll be killed.
Batman and Robin's crime is something that neither of them regret.
Batman is prepared to kill to prevent people from learning his secret.
