I think some of them intentionally model themselves after the evil characters in fiction. I remember seeing Musk talk one time about how he loves the game Deus Ex.

Of the 5 users of the Palantirs that we know of 2 are good, 2 are evil, and one is tragic.
AFAICT the consensus is that they are a very catholic concept and an illustration of what could happen when you use the weapon of your enemy and in general don’t understand the means you use to your end and how even strong people deceive themselves willingly when they think they act for the greater good (movie Denethor is a fool but book Denethor is wise and shrewd, but misguided by despair and Sauron’s manipulation).
