Harry Potter and the Plot Twist

What if it wasn’t Voldemort who wanted the Sorcerer’s Stone?
What if it was …
… Dumbledore?

I liked Harry Potter and The Sorcerer’s Stone. The book and the movie were great!
To be honest, I didn’t want Harry to be the villain and Voldemort be the hero. I just made Voldemort and Dumbledore switch places in the story line. And it made a little bit of sense.

I mean the guy is old, so it would be a good reason for him to go after the stone to become immortal and powerful, right?

… Right???
