The Source
So what is the source of the power of Satan? Is it hate rage pain suffering? Well the answer is simply all of the above. You see when Satan tempted the first woman into falling to sin he made a contract with the whole human race. He who granted humans the fruit from the forbidden tree would always have a mark on the human race from then on. What is that mark you say? Well it is in fact Orginal Sin. Orginal Sin you see is the blemish that the whole human race has on itself due to eve's fall. While this sin can be washed away via baptism Eve's sin leaves us wide open to future sin. So basically through Eve's failure she damned the whole of the human race to be no longer perfect and in such being open to sin.
So now that you have that little bit of knowledge i will give you a bit more. As Satan has been freed from his imprisonment he has slowly nurtured the human race into falling deeper into sin to further fuel his influence and continuing the fueling of his natural powers. Now i should point out that Sin is not the only source of Satan's power. Satan also gains some strength from strong negative emotions wrath lust greed rage and the like. Satan also gains power through War and crime or other such violent acts.
