[Sephiroth can't feel so black-and-white about the monster, especially given that's what he was called even before he lost his mind. If they would mind their own business and not try to harm people, he wouldn't attack them. He doesn't go after the monsters that are being peaceful.]

... That may be true.

[Maybe with time, he can come to see it that way. If only it hadn't ever happened. But it did, and it has to be dealt with.

He looks the monster over as well. They definitely finished it off.]

How do I not feel guilt? I try to go on anyway, but it's always there, sometimes more in the back of my mind, sometimes more prominent. It feels ... wrong to be alive when they're dead.
