The biggest difference is the Knights of Ren called the Dark Side of the Force by a different name. They call it The Shadow.

Couldn't agree with you more, another wasted potential in the disappointing sequel trilogy

Pretty much. That’s exactly it in universe actually.

Honestly they would have served better as more of a mercenary sub-faction that was hired by the First Order.

Those guys don't even use lightsabers

^Thats why they’re so lame.

I rest my case. You have earned yourself a pretzel. 🥨🥨🥨

Why didn’t they save a lot of time and call themselves The Knights of Lame?

I’m not sure they really didn’t hunt Jedi but artifacts also weren’t the inquisitors already established in lore by the time the force awakens came out

^yes think about that for a bit. After the Inquisitorius collapses along with the Empire the Knights of Larp was formed as the cheap Chinese nock off.
