Everyone is the narrator of their own fiction – and no one ever casts themselves as the villain in their fiction. Never, except perhaps in cases where there is some sort of mental disorder involved, but even that is subjective.
It’s just fiction.
We see ourselves as we wish to be seen, not as others see us; we see others as we wish to see them. And because we’re never the villain, someone else ends up being that villain.
Reality starts where that fiction ends.
