Obsession Or Curse?

"Let me tell ya something,why this things never work on me? Because i had the madness hahahaha!",i laugh as i kick the women's leg down as i got my bat and slam her in her head.I laugh as i watch the bleeding women on the floor.
"F-forgive me Harleen...",the women said as i caught her words.
"Harleen? Its not my name anymore..its Harley,Harley Quinn!",i said as i slam her even more as she was dead on the ground.

I walk as i laugh.Thinking what would i do next,but the thing is..how? This mind is getting me off..i wanna know if this is obsession or just curse?
