C here, I still think about you a lot Ink
I don't like you, and I don't think I want things back the way they were because I can't quite trust you anymore, but I don't hate you as much as I claimed to — I never did. I was angry, I guess, and hurt, even though I knew damn well I was far from perfect myself. And it's not like I don't get it, if anyone knows what it's like to be manipulated by XGaster it's me haha. I was so resentful towards you even though you were my best friend before that and I loved you a lot, I think I just couldn't admit to myself that I don't actually hate you because I was with Nightmare. I needed to justify seriously fighting and hurting you in my head, y'know? And going "that's not your best friend, that's a spineless traitor" made it easier.
At the end of the day I don't think we could have become friends again, and I really didn't want to anyway. Setting all the hurt and betrayal aside it wouldn't have worked because I swore myself to Nightmare and I was fine with being a bad guy. I guess I'm a real shitty person, shittier than you since you let Dream and Blue convince you to try to be good while I decided that I just...don't care anymore. I gave up, so I guess I admire you for being stronger than me? I dunno. I took the easy way while you actually put work in to be good.
For what it's worth I forgave you a long time ago. We're not friends anymore, but I don't hate you, and for as much as I liked to insult you and call you a fake hero I knew deep down you're a much better guy than I ever was.
