So … I don’t think this is a simple question at all.
Let’s start with a clear definition of power. Power is a resource that can be used to work towards a purpose.
Power is a tool-- any tool. Any tool at all.
Money? Power. Physical strength? Power. Keen wit? Power. Charisma? Power. Weapons? Power. Wisdom? Power. A technician’s toolkit? Power. A sharp rock? Power. A heavy rock? Power. A pebble? Power.
Everyone has it, every living thing. Those we think of as powerful just have more, and often a wider variety of forms.
Power can be thought of as corruptive for two central reasons. First, there’s the human reaction, not to power, but to status. Second, there are the base requirements of possessing and maintaining power.
First, status. Human beings as a species are typically wired to feel empathy for those whose opinions matter to them: those of equal or higher status. This is natural: in general, a human is more likely to suffer or perish at the hand of a rival or the whim of a superior than because of a subordinate. It takes an unusually empathetic individual to really feel empathy for those whose opinions aren’t immediately important. Thus the upper castes of any given society are likely to have a reputation for callous and selfish behavior-- not because they’re psychopathic, but because they’re just normal humans and don’t have as many superiors or peers.
This is the cause of a lot of trouble, but it seems to be just how we are.
Then, also, it’s the nature of most, if not all, power that it doesn’t maintain itself, at least not for long. Money, skills, social status, physical strength: all of these require attention and effort even to maintain, and most who possess such things want to see them grow. Most methods of acquiring and maintaining power involve either exercising that same power or leveraging power of a different kind.
This can get pretty ruthless.
In general I think of LUMEN as a pretty benevolent alliance, but I also have seen firsthand the leveraging and expenditure of military resources and personnel (forms of power) for the sake of reputation (another form of power). Acquiring and maintaining that reputational power is itself aimed at greater security for our resources and personnel: having a reputation for having teeth and the will to fight and kill is a good way to keep from having our teeth and will too-frequently tested.
But it comes at a price in human suffering and death even just to more-or-less maintain. How much more to actively expand it?
Most power that puts a person in any kind of exceptional position is like this, to one degree or another. A pilot risks others’ lives and their own material to build even a basic set of resources and skills; an empire plays similar games, but on a scale so vast that the costs involved in scrabbling for any kind of edge can seem obscene.
The whole world can be described in this way, without really being wrong. (But being, I think, insufficiently right-- there’s so much more to life in this universe than that.)
For these reasons, I usually don’t say so much that power corrupts as that I don’t feel it does favors for those who have it. It doesn’t necessarily corrupt, but it tends to harden the heart by increasing status and then encourage ruthless conduct in its maintenance and growth.
The results might often be described as corruption. But I don’t think it’s as simple as either making people bad or revealing their true selves.
It’s more like, the more power you possess, the more of your focus, your time, your self you’ll have to dedicate to its maintenance and growth.
And some people perhaps end up paying with basically all that they are: focusing so much on power that they can no longer see the world in any other way. I don’t know that that’s corrupt, necessarily, but it seems like a sad way to spend a life.
I’m not sure I can think of a more empty life than one consumed with seeking power for power’s sake.
