I'm trying to stay out of this for the most part, but it was established that just saying sorry wouldn't cut it.
I dunno. One of the things that popped up in the story was that the fruit was not some verboten may never, ever be taken thing, And that if a Gabriel-in-good-standing had wanted the fruit, he could have just requisitioned one on his own authority. And then at the end, when the poor angel who had been nothing but polite and respectful was having a BSOD moment, I would have tried to repent as much as I was able. Out of compassion and pity if nothing else. Because he was standing there in front of me, suffering. And using "want the ends, want the means" is a bit bullshit if the ends (a fruit of knowledge) have the means (get it from the garden
somehow), but that somehow didn't actually require theft, and the theft was just a lazy, unnecessary step made along the way. And if I couldn't have convinced myself, that's alright. I would have said the lie anyway, because Zauriel seemed to be personally hurting, might have accepted it because if he did, that would have freed him to leave.
And if it didn't work fine, at least you tried. I mean, OL isn't a fairy. He is perfectly free to lie, and has done so before. It would have been a miniscule moral compromise for Paul, compared the the humongous moral compromise he was asking from Zauriel when he tempted him to literally eat of the forbidden fruit. It is also easier than offering to accompany him to the gates of the silver City and wait while he reports, or transition back into Eden so he could relay a message through one of the angels there.
The whole scene made me very disappointed in Paul. Because he was so much crueler than he could have been. And because it was a lie. There were so many more choices other than take the fruit or
"stand there paralysed until I leave or you're given alternative orders.
" The devils first lie is that the only options you have are the ones he puts in front of you. For someone acting as an advocate of free will, he diabolically made sure there was as little free choice given as possible.
