There's something reluctant in his tone when Angeal continues, though his expression is reasonably steady. The worry-lines seem a little deeper, but that might just be the light. "And because of that, because he's finding .. a new place for himself, making bonds, forming friendships, I don't want to destroy it by forcing him to remember who he used to be. Who we are is in a lot of ways dictated by our memories. It shapes what we do, how we feel. If he remembered, he might become who he is again, save now he'll know he's responsible for the deaths of perhaps tens of thousands of innocents, and who he is this very moment may die." He makes a small helpless gesture. "I don't wish the man he was to be punished for who he's become, and who he's become deserves a chance to find a life for himself. My friend is dead. Your friend shouldn't have to die too."

Remembering would take it all away, in one direction or another. He makes it sound reasonable. It isn't his problem, he's nobody's warden, he has no say in any of it.. but as a friend, he didn't want Sephiroth to suffer more. Let the crimes sit on the shoulders of the one who made them.

Maybe Wardens had a different perspective. Maybe they had to, because of their jobs. "..Of course you would. That's what you do, when you know a friend is upset."

But the problem goes back further than one argument over Sephiroth's fate. "But this ship doesn't seem much like it's interested in respecting people's privacy, from what I can tell."
