you were fighting DIO, and you were losing the fight, but you got a chance to survive after he said...

DIO: "THE WORLD! Finish (him/her)! I need to suck the blood of Joseph Joestar."

he then went to do so, leaving you alone with The World

The World: "I need to exterminate you..."

she prepared her fists, ready to punch you, but...

The World: "But... If you do something for me... I might as well let you live and tell my user you died."
