Actual use of Sith techniques seems to turn people evil at ridiculously accelerated rates. At least in-universe it seems that sensible people would write off this attractive-sounding philosophy as window dressing on an extremely damaging set of psychic techniques.
Sith philosophy, for reference:
Peace is a lie, there is only passion.
Through passion, I gain strength.
Through strength, I gain power.
Through power, I gain victory.
Through victory, my chains are broken.
The Force shall free me.
