Kindred,
Unfortunately for your unfortunate friend, there is an inverse correlation between feeling powerful and being peaceful.
The more power one feels, the less that person receives in love and peace.
Why?
Because that person is blocking the love and peace (and the Holy Spirit) with power.
Therefore, more power, less sensitive to self, the Holy Spirit and humanity.
Brute force, aggression and power does not translate into intelligence or wisdom, because not connected to the mind or spirit or the Lord in Holy Spirit.
