The truth was, that Sideous was not sure that Vader, or any of the inquisition, would be able to track down and deal with Pathe the Hutt. Old enough to have met Darth Bane in person and to have seen the Russan Reformations when he was still young, the hutt was an oddity among his kind. Or perhaps merely of those that gained their fame in the greater galactic stage. A scholar, a mystic and philosopher who had managed to avoid being swept up into the politics of any one sect or another and later on avoided capture by the Jedi shadows despite the fact said hutt made a study of the entire force.
Quieter in many respects than his kin, but also far more worrying because it. Strange stories always circled around the Hutt, of the force related relics he had either crafted or recovered, keeping them aboard his mobile station that was as much a grand museum as it was a habitat. Some of his predecessors, in their holocrons, wondered if the tales he had shared drinks with the spirits of long dead Jedi and Sith alike, knowing how to call them from the embrace of the force for little get togethers... or to help him in his study of history.
Which, ironically enough relates to how the man that was an Emperor of the galaxy had first met the hutt. After all, Pathe did occasionally accept a position as a guest lecturer at a handful of universities, even if he had to adjust parts of said lectures as the Jedi became more and more dogmatic over the centuries.
Truth be told, it was the first time that many on Naboo had ever actually seen a hutt, as he was engaged with the lecture, of the impact of the broader historical trends through the ages. But, there was a particular question that Seev wanted, no, needed to ask, as the hutt pointed to him, beckoning him to ask. "Why is it that you refer to the Sith as a Jedi sect? Are they not entirely different things?"
The hutt laughed. The booming laughter was etched into his mind. "That is indeed the official policy of the Corusanti temple, but is often the case, they are technically correct while ignoring just why that is. The closest relevant example would be humans and the various near humans. While in some cases this can be a case of convergent evolution that often can interbreed, in others the differences are minute enough that it is likely environmental pressures or genetic engineering in the past resulted in these differences."
The hutt paused, the assistant with him adjusting dials. "But, the Sith species, from which the later orders would take their names, was its own biologically and culturally distinct culture long before they rose to galactic infamy. However, after the end of the Second Great Schism among the Jedi and the end of the Hundred Year Darkness period, the surviving dark jedi were exiled. And in their exile, they found the Sith, enslaved them and interbred with them. Eventually, the term Sith came to mean, at the time, one who followed the traditions and culture of the Sith people, with of course, the desire of revenge against the order that exiled them."
The hutt paused. "In truth? The Sith Empires were founded by dark jedi conquerors who established a cult that outlasted the memory of their exile until the events that would lead to the Great Hyperspace War. However." One finger rose. "It is also true that through the centuries that the sith tended to recruit fallen or dark jedi, many of which would eventually rise to positions of power. This is, for all that the sith stand to repudiate the Jedi, they are also fundamentally relatable to the jedi. A dark mirror in many respects, different and similar enough to be two sides of the same coin."
It was then that there was a question asked, a question of redemption that made him want to sneer at the naivety of it, as the hutt seemed to take great amusement in it. "Oh, while indeed possible, the nature of the Light side to strive for purity and certainty tends to make redemption an impractical proposition. After all, you cannot have a pure cloth once you have stained it with ink."
And even decades later, Sheev could have sworn that Pathe had been looking him right in the eyes as he spoke, before he turned to answer more questions from the eager and interested students.
Their next meeting came when he was a senator for Naboo. A simple tour of an art gallery, and one where he managed to have a moment of privacy with the hutt, as they both admired some of the art, of how the artist was attempting to convey a sense of grace and power. "You know, I had attended one of your lectures, some years ago at Theed," There was a neutral hum from him, as the slug looked the pieces over, parts of them seeming almost glowing if you looked at them the right away. "I was curious, of your knowledge on the Sith..."
Now, he knew that the hutt was amused, one hand raised. "I assume you would want to know my sources for the older orders, given how you could just talk to Plagueis for the more modern history?"
A fission of fear, of uncertainty, of the the fact that the hutt revealed that he knew, so casually, as if possessing the secret was of no import. "And before you try little spider, I have said no to each link in your chain that wanted to drag me into the absolute clusterfuck you call a grand plan. And." He turned, and those eyes were deep and still pools, as he spoke. "I am still here. If its any consolation?" The slug shrugged, as he moved. "Your probably going to win for a time. But, I have heard your story a thousand times before."
The tone was grating, it was knowing... it was dismissive and worst of all? There were traces of pity of all things, from a HUTT in that tone. And so, Sheev hissed. "And should you then be so dismissive, if you think you are so sure that we shall win?"
How the hutts eyes burned, twinkling like stars as he turned his head. "Ah, you misunderstand, as you remind me of some of my younger kin, who win it big, and then proceed to choke on their prizes, thinking that force and fear are all you need to last in the big time. I tell you this, that it may save your life."
It was the last Palpatine had ever seen of Pathe the Hutt in person.
Years later, as he fell to his death, that mocking laughter ran in his ears, lightning racing from the tips of his fingers, before the heart of the Death Star consumed him. "Heh, how's victory taste Sheev?"
