A non-betrayal music theme for Kain

So, I'm writing a fan story that takes place 2 years after FF4 (yes, I know TAY exists, but I'm ignoring it; please don't ask), and Kain is a major character in the story. I like to listen to music while I write; however, Kain's theme (Suspicion) is not suitable for the story. Anyone have any suggestions for songs from FF games or any games?

Edit: I found one for him. Someone on Reddit gave me a hand. Thanks, though!
