Destroy those wealthier and more successful. Destroy those who disagree with you. Destroy those who dislike you. Destroy those who have humiliated you/embarrassed you/got the best of you. With power you can get back at all of them. All you nee isd for the powers that be who could stop you tlo look the other way. Then get a public willing to be destroyed and you can do whatever you want whenever you want to whomever you want and no one will stop you. Enviable position for a demon. SIGH.
