What does "I Did Something Bad" by Taylor Swift mean?

"I Did Something Bad" follows the same formula that we heard from "Look What You Made Me Do" or "...Ready For It?" Taylor Swift has turned over a new leaf, and is now a tougher, stronger, harder, version of herself. She's not going to roll over for anyone or wait for someone to come save her. She's ready to take control of her own life even if it means destroying her enemies.
