Why shouldn't you change? Because you hurt someone, someones, maybe badly? And you feel like the rest of your life has to be some memorial to that, to the bad shit you did? Nah, man. Everyone gets to change. Not everyone else will accept the changes, they might still see all the shit you did and think it's enough of a reason to hate you, so let them. But you still get to change if you want. Yeah, like different perspectives. Two people can look at you and see someone different, and it doesn't make them wrong. But the important thing, and I know it sounds like bullshit, but the important thing is how you look at yourself. Because everyone outside of you will have their perspective, but you're the only one in there.
Whatever you did, girl, don't forget it, but let it go. Come back to it, like you visit a grave, and remember whoever, but you don't sit there, rot there beside them. You know?
