“Serious” lol

No. Darth Bane implemented the Rule of Two for two reasons, to ensure the Sith could stay under the Jedi’s radar and operate in secrecy, and to turn the infighting from a weakness into a strength.
Prior to Ruusan, the Sith’s greed and ambition often led to several weaker Sith plotting together to take down more powerful Sith in higher ranks. That meant that over time, positions of power were filled by weaker Sith then before, meaning the order bled itself out.
Bane though, as the sole surviving Sith after Ruusan, set up the Rule of Two so there was only one apprentice at a time who had to be more powerful than their master in oder to overpower said master, leading over time to stronger and stronger masters and the order again gaining strength to exact its revenge.

How would you categorize the community rules “Be nice to each other”, “Don’t insult each other” and “Don’t call for violence”? Just or unjust, dair or unfair, sensible or dumb, expedient or not?

Yeah, the good old “You are a Nazi for following rules”-thing. Because everyone who follows rules does so indly, except for oneself.

Oh, yeah, “They removed my comment where I’m just an asshole and telling people to kill themselves, they are such zionists 😭”

The fuck is wrong with you guys?
