I knew a kid like that growing up, & it shocked me. He was an under-privilaged kid that grew up to be very frustrated & was self destructing the last I heard from him.
It's way worse for Sid though. (cue ominous music)
He was a spoiled & entitled rich kid from generations of nobility.
Lol... great topic... so I'm going to go off teh cuff here a bit.
Maybe impossible for regular folk... but "maybe not" for those born into generations of noble entitlement. Once teh "my way or the highway" mindset syncs in... it's very powerful if you've got status, bank, & nobility behind it. The only thing that breaks down that mentality for common folk... is that we need the cooperation of those around us to make our dreams happen.
Sid just effectively bypassed that dynamic.
With that in mind, it's easier to see
how a dictator at heart could rise to this level without a "trauma experience" fueling it. He's just doing what's best for us... whether we agree with it or not. He's just simply bypassing the dynamic that he needs anyone else's cooperation & he'z making moves to manifest all of our dreams for us. (The power of positive thinking yeah?)
I hear you on wanting details from his development, because not much is known except that he started relic hunting as a young man which led him to Plagesie. Maybe they will do a backstory... but I'd imagine it being the story of a young super-entitled nobleman of many generations, being frustrated by the slow effectiveness of democracy, but his parents being over-worked at that crucial moment when young Sid innocently inquired as to why democracy was so difficult to navigate in order to get things done.
So the young Sid went to his room to play with his bath girls while developing the idea that the sheep need a totalitarian rool to make them comply to a quick & effective dictator that can make things happen.
He literally used that dynamic against the democracy in teh prequelz... when their slow response (too HIS attack... lol) was shown to the whole galaxy to be un-effective. Brilliant!!! So it was obviously something he considered greatly.
The problem is that this "quick response" mechanism in government requires
one person to make those decisions... & if they're a Sith... well we know the rest.
For me, a common backstory for Sid... of a sniffling kid having his heart broken by a hot young Gungan isn't "my Sid." He probably had tail lined up for him his whole life, similar to the prince's bath scene in "Coming to America."
That said... maybe "the one" he really wanted... got away, but I don't feel that "confusion/frustration" is his drive, and he didn't surround himself with hot nude women once he got his power. (to surprisingly absent levelz
)
His drive is too "untethered" for something like that to be his main drive. It's cold hard control... dispite the sacrifices others have to make. As long as you agree with me & let me do whatever I want, then you'll have no problem... (unless you rely on your natural resources that I need, in which case I'll just confiscate them & allow your people to die. It's nature.)
So It's more like being handed the world on a silver platter but wanting more, despite anyone else'z needs. I'd say that he had Sith tendencies & ideas way before he even was exposed to that religion. So he was primed & perfect for the spot... & his "off teh chart midichlorian count" helped that too. (fueled by the Jedi imbalancing the force to the light side & so had to correct the balance by creating Sid. Teh unsung reason for teh rool of 2, more power for teh few, while the Jedi's light was spread among thousands)
It might actually ruin it for me, if there's some traumatic event that swayed him
The way the mighty Vader'z backstory was resisted so much... by showing him as a frustrated & confused kid that was basically tricked into becoming a Sith wouldn't work with Sid because he never reconciled for anything.
With Vader's backstory though, it waz necessary that he was conflicted... otherwise it wouldn't make any sense when he turned at the end. (woops, spoiler)
Sid will never turn (not even after his next resurrection
) & so that backstory serves little purpose outside of curiosity.
Sid's natural entitled drive was perfect for the Sith religion going in. He didn't need to be twisted to become a Sith... he was already naturally & wholeheartedly twisted in that way... and that's why his power became so great and persisted for so long. His natural tendencies fit right in... & he wasn't weighed down by personal luggage.
Big difference there... & I'm not sure I would want anyone to alter that deal with Sid's backstory.
He did it for the common good, despite our pesky insistance of having our own ideas... that's all we need to know.
