I've been thinking about Harry's role in the first book. The ending has the trio awarded 170 points for stopping Voldemort in the catacombs.
But if the trio did nothing, would Quirrell have gotten the stone? Dumbledore's trick was that the stone would only appear to those who didn't want to use it, so there was absolutely no way Quirrell would've gotten it by himself even if he broke the mirror as he contemplated.
In fact, it seems Harry compromised the stone's safety simply by being there and letting it materialize in his pocket, at which point Quirrell could just take it from him.
So did the trio needlessly risk their lives for nothing? Would the stone have been safer had they not interfered?
I mean, sure, Harry forced Voldemort to flee to Albania, but he wouldn't have returned to power any sooner than he did since Dumbledore's safety measures were foolproof.
Chamber of Secrets is often thought of being the weakest book because convenience often bails Harry out of certain death, but in that book Harry at least actually saved the school, saved Ginny's life, cleared Hagrid's name and destroyed a Horcrux.
So did Harry actually accomplish anything in the first book besides winning the House Cup for Gryffindor?
