That is fair. I personally like the idea that the students gathered around the ruined hut, thinking Ben killed their master, and started picking sides until someone struck first. Like you said, it doesn’t totally pin it on Ben.
Though if you went this direction, it would be nice if there was some hint that the Knights in TROS were the other students. Nothing really gives us that impression. No sign of force sensitivity, no lightsabers, no relevant dialogue, etc.
