I know this assertion seems immature and I almost feel like one of those insolent children that shouts controversial things just to be controversial. Given the subject this is inevitable. I intend this not as a joke but as a serious train of logic.
If there is such a thing in the universe as "good" and a diametrically opposed force called "evil", the former represented in purity as God, the latter as Satan, then they must be of equal power - for there can be no opposites in existence that do not perfectly balance and compliment each other. There may only be the illusion of an imbalance from certain narrow perspectives but ultimately they must be equal.
