I got more info here http://www.mariowiki.com/Chaos_Heart. First, it says, "The Chaos Heart can only be destroyed by either killing the controller , or with the concentrated power of love embodied by the Purity Heart. " The pure hearts were made to destroy the chaos heart, not to power up the user to the point of which they could defeat the wielder of the chaos heart. It also says, " The three remaining heroes use the Pure Hearts to negate much of Super Dimentio's Chaos Heart-derived power, allowing them to defeat him and free Luigi." They don't gain power, they take Dimentio's away.
