Who gives a fuck about "Normal"? It doesn't really work the same way here. Normal for me is being ten feet tall and blue, but for some of my family, it's using magic as easily as breathing, and for other people, it's switching skins as and when they can. Normal's different for everyone. You just gotta be you.
Pretending you didn't do horrible things is understandable, not shitty. The fact that you're still worried about them, that's a good thing! If you just dismissed them completely, and you weren't bothered by the memories at all, that's what you don't want to do.
And yeah, what Maryanne said about wishes. Be careful with them.
