Well perhaps Penelope looked into the future with the Time Machine and sees that Bentley dies (Although later in the game they manage to prevent that) and she blames Sly for that because of all the danger that he goes through. She helped Le Paradox because she thinks it will stop Bentley from dying which is why she said "I'm doing this for you." meant.
