Finally, he's talking her language! Asking what is permissible, what should be supported or opposed, in what conditions she would have acted differently than she had. These are safe, sane, rational questions, about rules, without any on-the-spot emotional decisions.
"Those are good questions! What it would take is for me to think the alternative to things as they are would be better, and that it could be achieved, by my actions or my order's actions or even by all the Iomedaeans and some of our allies acting together, in which case I would try to convince them about it. And of course I wouldn't do or permit the things expressly forbidden by my oaths."
"I think it's overdetermined, and not a close thing at all, that I should help Mendev stay together in its current shape, or to reform it from the inside. I'll go over several reasons why, and I think even some of them being true would be enough."
"First, Mendev is not a monolith. Even ignoring all the foreign crusaders and the churches, the government and nobles and most local people don't cooperate nearly enough to think of them all as one organization. Which means I can help some of them, and oppose some others, without worrying that I'm helping perpetuate an Evil system. Or in my case, while fearing that a system that I think is much better than nothing will collapse somewhere else, while I'm not there to stop it."
"I'm willing to catch murderers in Kenabres. There are Mendevian generals out there doing some Evil things I don't condone. They work for the same government as the Kenabres city guard. So you might think that by helping out in Kenabres, I free up some of their men and their funds to go to the generals."
"But the Mendevian state is not nearly well enough run to actually do that. I'd need to prevent half of the crime in the city before they notice. And even then the freed funds would be used locally by Hulrun, not given back to Nerosyan."
"Even when I turn in a murderer for Hulrun's judgement, I don't free up some of his men and funds for other tasks, because they very rarely conduct investigations into things other than security threats like cultists or very large crimes like mass murder, things that affect the whole city. They can't afford to chase down every murderer, because Hulrun considers his main goal to be exposing cultists and other traitors, and that's not a fight he's comfortably winning."
"It is true that, since I help - improve the city, by leaving more people alive and loyal - there are second order effects on the rest of the country. Kenabres is a vital city for the border defense and the Crusades, and improving it gives those generals a little more slack. But I believe the first order effects dominate. If I save a man's life, the army doesn't grow by one man, and I'm not enabling a general to send another man to his death. Not unless you think it's bad for people to be alive in Mendev at all, like - every additional living man goes into the army? I don't think that's true."
"Second, if I'm considering whether to help keep Mendev afloat, I have to compare it to the alternative where it sinks, not to some blank state of neither Good nor Evil. If the state of Mendev collapsed, it would be overrun by demons, and most of its population would be killed or tortured or worse, and the rest would become refugees. Just as happened in Sarkoris. And that is a far greater Evil than any committed or allowed by Mendev, so it's easy to choose the lesser Evil."
"You suggest that fighting the demons directly is enough, and the state of Mendev doesn't need to be propped up behind the lines. But the army that holds the border is manned by Mendev and funded by Mendev's taxes, paltry as they are compared to many other states, and most of the foreign crusaders are Mendev's allies. Everyone who wants to volunteer, and can afford to, is already doing that. We can't have the army without the state, and we'd have lost the crusade without the army."
"Fighting the demons is of course crucial, and I did spend several years doing that, and rotated in for shorter shifts in all the years since but one. But some effort must be dedicated to other things, and in my judgement not enough effort was going elsewhere."
"Third, I think it's much easier to reform Mendev from the inside, by working with the authorities without working for them, than in any other way. You speak of Mendev's existence preventing something better from arising, and - I can't imagine what that might be. Even without the demons, even if the people were not exhausted and impoverished by a hundred years of war and the Sarkorian refugees, the only successful revolutions for Good have both been against a country ruled by Hell. Revolutions against lesser evils don't tend to end up improving very much. What do you imagine could exist instead, if Mendev collapsed but the border miraculously held?"
"I'm not alone in this. Many people outside the Eagle Watch work to improve the system, or to help people directly. Some people donate money to us, instead of more strictly military crusading orders, because they think our work is valuable. If the demon threat disappeared - if we had another thirty years of peace before the next big war - I think we could improve the country significantly. If enough people agree and cooperate we could reform Mendev instead of overthrowing it. And if we have enough support, I expect Queen Galfrey and her political allies would be on our side."
"Fourth, and most importantly, I don't have to make this judgement myself. I can look at what all the other paladins, and Lawful Good people, and wise people of every truly allied alignment, think about it. And even better than that, I can look at what Iomedae thinks about it, because She is much wiser than any of us, and because this obviously greatly matters to Her. She has given Mendev a clear sign of approval in putting and keeping one of Her strongest paladins in Golarion on the throne. Such strong paladins are costly to Her. If Queen Galfrey is more useful as Queen than smiting Evil, that means she is very useful indeed. And it's quite plausible that Mendev would not have lasted this long without her on the throne, considering the people next in line."
"So even if Mendev seemed - of marginal utility, to me, I would never consider myself more qualified to judge it than Iomedae Herself."
