"Ah, a proactive would-be god-slayer. They always have very... intense personalities."

It's not that Cecil has an issue will killing gods by itself. He's not that much of a hypocrite. But he's also spent months stuck in a world with plenty of people who shared that goal, and frankly having something in common with Kefka is no endorsement.

Goodness, he truly hopes Arceus knows better than to ever bring someone like Kefka over here, even if it someday decides to summon the dead vessels of a mad god.

"Happy? No, certainly not. But I'd certainly not feel absolved in the first place, if I'd simply died without attempting to make amends. Thus, I'd appreciate the opportunity to help others, even if I could only offer a single drop of kindness against the ocean of pain I'd caused."

No matter how much of a relief it is, death is no absolution. That much he's certain of. It may end a threat, become a necessity, but it does not bring back the dead, nor does it rebuild what has been destroyed. Allowing the people of Mysidia to kill wouldn't have helped them.

Playing along with Golbez's suicidal wish wouldn't have helped him, either.
