That is a smaller number than she was expecting and somehow it doesn't make her feel better at all.
(For a moment she feels like she's fifteen years old again, watching a kitchen-slip beg incoherently for her life as if anyone will listen, until eventually she can't beg at all.)
Four is — it feels almost possible that there's an amount he could suffer on Golarion that could set things right, not right enough that he'd deserve to be a priest of Iomedae but right enough that if he got the Final Blade afterwards it wouldn't feel fundamentally unjust that he was being spared the suffering of Hell. Not that he's going to Hell, apparently, but still. It's a fathomable amount of Evil, rather than a completely unfathomable amount.
None of which even slightly excuses being a priest of Asmodeus.
Valia would say, did say, that Evildoers who keep seeking power should die for it, and it's hard to see becoming a priest again and joining the convention as anything but seeking power. Alicia would say — well, she could just ask, but she's pretty sure Alicia would say — that if he really has given up serving Asmodeus completely, it's better to put him to work helping people who deserve it. Raimon would say that justice does not come to the defense of people who are tortured to death by Asmodean priests, and that that's wrong.
The azata would say that no matter how many innocent people he's tortured to death it's wrong to kill him if he's stopped. She really doesn't feel like listening to the azata right now.
There's a sense in which this is all kind of irrelevant. She's almost certainly being watched; if she tries to hurt him she'll die for it, and it won't even work, they'll just put him back. (She feels a flare of anger in her chest that there are so many innocent victims who stayed dead when Chosen Artigas is not just alive but resurrected.)
...Delegate Ibarra was in the hall when Delegate Fraga brought it up, and for all he's Evil she's pretty sure he really does hate Asmodeus. But trying to get someone like Delegate Ibarra to help give Chosen Artigas what he deserves feels obviously wrong, and anyways the idea of talking to him feels even less appealing than the idea of listening to the azata.
She wonders how he did it. Her priest was never very creative, with the torture, and it's making it kind of hard to imagine him getting what he deserves with any degree of specificity. Flaying would work, it's not like it has to be exactly the same, but there's something satisfying about the idea of hurting him the same way he hurt his victims.
"...What were they like? The — the four innocent people, I mean—"
