Which Psycho could I....?

[haruki_emishi]

my friends and I are going to a cosplay convention this month. And so I need help on figuring out on which crazy guy I am going to go as. I have SOME choices but I need outside opinions if that is all right. And since this is a place for psychotic dudes I thought "why not?"
My choices right now are:

.Scarecrow
.Joker
.Light
.Schrodinger (from Hellsing)

Here are my most recent pics of myself ^_^ or over the past year. (behind ze cut ) I also apologize because you have to copy and paste the links.
