Darkness:
"So (chew) what...i like chocolate. I don't give a bloomin' f*ck about diabetes. That's a mortal's problem not mine."
...and besides...everyone's addicted to something."

In order for Darkness to remain physically in the world of the living...he must eat the first substance that he was exposed to when he escaped Hell...i know its f*cked up right?

Without chocolate, Darkness becomes very bitchy and temperamental. eventually he might just rip your head off...but it's nothing personal...its the withdrawal symptions.

Oh yes i am dead serious...GET IT "DEAD"? LOL.

So it was a little girl's chocolate bar....and i don't think he is going to give it back.
