Everyone has been corrupted by Exeller. All but you, you seem to keep escaping from certain death. So what does he do?

He sends the one person who you care about, Cream. She was lost in the corruption too...

And so when she saw you in Green Hill, which was now engulfed with blood from all the animals and other things. She spoke in a dark tone

"I was sent to kill you...and I do not plan on failing...!"
