Griffith would prefer to never die at all, but if he has to die, he would very much rather not die in a fire, a preference which reality is ignoring.
The lab door seems to be locked through some mechanism his key isn't working for, and his attempts to extinguish the fire have failed, and nobody seems to be responding to his screaming, which was initially an attention-getting attempt and at this point is mostly due to pain.
There's something his patron mentioned about making mental statements at Asmodeus that was a good idea? He really doesn't have much attention but a bit of him is attempting to think "Asmodeus, I don't want to die" in an outward direction.
He doesn't get a response, and the pain continues even as his higher cognition fails.
