Obviously the power to make people's lives better or to create beauty is a good thing.
The original question involved the lust for power
Lust is intense desire; overwhleming desire.
The term has been misused to connote a positive condition ( e.g. lust for life) but, at least to me, it is a negative state of mind. No good comes from wanting something so intensely that the desire either overwhelms rational thinking or instructs one's every decision and action.
Lusting for something guarantees the perversion of that which you seek. Anyone who truly lusts for the power to do good is fooling themselves or others. They are lusting for the power to control
other people's lives.
It (lust for power) has certainly been a common element in the human condition for a very long time, and I would suggest that it is the primary reason for so much of the world's suffering.
People talk of religion being the bane of humanity, but it is individual's lust for power, using religion as a vehicle, that is the canker. Religion, nationalism, ideology, they have all been used as vehicles for obtaining power.
