Nobody wakes up one day and decides to be the villain.
Something has to happen.
Something has to shift.
I wonder if, eventually, you grew tired of always being the hero; if you gave all your warmth away to people who left you cold.
So you stopped.
You rewrote the story.
You rearranged your constellations with smallest hope that someday, somewhere, someone would understand that just because you can save yourself, doesn't mean that you don't long to be rescued.
