Darkness or Light? Philosophy in Knights of the Old Republic.

Yes, and I think no one will argue that the life of a Sith is easier.

The life of a Sith is actually much more difficult overall... because he has to think and strive for his own goals... develop complex plans and perform the most dangerous maneuvers to achieve them... while the Jedi have it simple - whatever the Council decides, that's what we do... And the Council makes decisions with ten heads, but incorrectly... A clear example is the Mandalorian Wars... when the Jedi Council sat around doing nothing, while Revan called for the manifestation of individuality and for each Jedi to make their own decisions...

Take, for example, KOTOR, doing good deeds is difficult (and not profitable), while dark deeds are quite simple (+ profitable). That is, it turns out:
You put in a lot of effort, and then you don't get anything for it (that's just the life of a Jedi).
You practically do nothing, and then you even get money for it (this is naturally the path of the Sith).

Well, the authors of KOTOR are still far from the ideal scenario... they took a straightforward approach, where you get everything you need in the process of completing the task... In the films, it is shown how Palpatine spent years achieving his goals... first using corruption in the Senate and an alliance with the "not very bright" Neimoidians, then, as Chancellor, he arranged the situation in such a way as to create a huge army for himself in response to the separatist union that he himself created... and then he spent years trying to reach a critical boiling point in order to reveal his cards and "win" the Empire...
