Well, are you sure about this ?
To take a famous fictional example, in Star Wars 1/2/3, we can watch Anakin (thought to be the chosen one), going first to Light side, and then, to the Dark side... and becoming Darth Vador (the dark knight ?).
Who knows, maybe that's possible IRL !
I look at Anakin as potential, gets caught up in drinking his own Kool aid and starts down that route. He became fixated on the physical and started swimming against the current, ends up fulfilling the negative prophecy he was fixated on.
Now once it goes downhill for him, there's still that little Annie in him, his potential, that was buried. He ran with the dark side through the movies till nearly his end, where he sees the light once again. From there he switches perspective/timelines whatever you wanna call it, once he dies he's shown as a force ghost, the potential making it too the highest pinnacle of spirit that we're shown within that universe via the movies.
I think both would consider the other foolish, as they are both opposite ends of the spectrum. Sts using their powers more for personal gain with manipulation of the physical and it's inhabitants, while sto is working more detached in the abstract, seeing the foolishness/harm of full commitment to the dark side.
Now I would see each individual as a collection of archetypes each one with its positive/negative sides and each at different points of their development/potential. A proper understanding of the extremes of both sides while striking the balance physically, boots on the ground in order to utilize ones physical skills in order to contribute aswell as mentally/spiritually in order to stay above the problem giving one the higher ground.
Don't run out the clock with your head stuck in the clouds, and don't tunnel vision yourself with all the shiny stuff down here in pursuit of it.
Something like that in a roundabout way.
Nice to see you all again
