Yes its allow to use holy ghost to fight your enemy. When bible say pray for your enemy it was not refering to house hold enemy or those who do wish you untimely death because of your glory. Bible was actually talking about enemy of christianity who hate you because you are christian out of ingnorance or their believe. Example people like saul that later became paul when he was killing christians thinking he was doing God works then. Those are the enemies bible says you should pray for so they can know the truth. You can use holy spirit for good and negative prayer against your household enemy. But this is how to use it...when u need holy spirit to help or direct your way that is when u call it holy spirit which stand for the comforter. When u need it to fight enemy then u call it holy ghost fire,thunder or anything u feel like.. The bible is not against it..

Really
