Sith Question

[Alcuin]

No Sith ever survived permanently. Exar Kun managed to hang on as long as any of them, but only imprisoned in his temple; the same would be true of Naga Shadow. Eventually, life in the galaxy would have to terminate for any Sith, and then the result would be an endless agony in the Dark Side of the Force.

So, the question is: why bother? Why be a Sith at all? The end result is going to be worse than if you had ignored the Force altogether. No matter how much you enjoyed your time among the living or managed to hang on among the dead-but-not-yet-departed, you must eventually succumb to the inevitable fate of torture and madness that awaits the servants of evil, and worse, every Sith will be marked for more of it because he was a Sith and concentrated it in himself.

With such an inevitable downside looming, and with no way to ever reasonably expect that this bad outcome can be avoided, why be a Sith? Isn’t it the stupidest choice you can possibly make?
