"I've seen enough," Aziraphale said, words pulled from between gritted teeth - because 'enough' was a subjective measure so perhaps he could get away with it - "but there's a major difference between seeing and deriving any sort of - enjoyment from it. And my time with Caligula was not recreational, believe you me." He shuddered delicately. "I was trying to save lives. Thwart evil, and things. Sometimes work took me less than savory places."

There had been a few times, a few people with the Lord in their souls, whom he'd attempted to help (in the most bumbling and accidentally judgmental way possible) get out of the trade. Generally they hadn't been receptive. Then again, he never really had any money to offer and the job market in Caligula's time in particular had been grim. Obviously. Still, he'd tried. While studiously avoiding eye contact. It really wasn't his place, it was a human thing.

Cognitive dissonance being what it was, he had temporarily forgotten that he was human now, and would likely continue to have selective amnesia on that front.
