How much info do you think I should give my players

I'm going into my ninth session in our Kingmaker campaign. So far my players have managed to not kill and bring in for trials every single bandit except 2 (one killed, one escaped).

That's Haps and all the bandits that showed up at Oleg's, all the bandits at the Thorn River crossing, and a beefed up Falgrim Sneeg and a couple of rangers I gave him as an ambushing party.

I want to reward the utter non-murderhobo-ness of my PCs by giving them some inside information on the Stag Lord's operation, but I'm not sure how much to tell them.

My justification is information they learned from Sneeg and his cronies; I was thinking I'd give them a bit of the internal power dynamics between Akiros and Dovan - possibly give them a little bit of an edge in playing the factions off each other.

What are the forum's thoughts on this? I'd like to give some actionable intelligence, but I don't want to obviate the challenges either.

They'd probably know about the recent shift in command between Akiros and Dovan, like you mentioned. I'd guess they also know all about Beaky (while that's a fun surprise to spring on the PCs, it's the sort of thing I imagine the bandits would gossip about).

Also if the PC's don't already know, the bandits can probably tell them the standard information (ie about the Stag Lord's drinking habit, and the password)

I'd leave zombie hill for a surprise unless they specifically capture someone who regularly guards the fort somehow (any regulars there would know about it). Any more detailed information on internal politics is also likely lost on the bandits who spend less time around the fort. They might know rumors about the old man living in the store room, but I'd put the odds of that pretty low (again unless they capture a bandit who is a fort regular).

Seerow hits it pretty much on the head. These are bandits we're talking about. They are not likely to have much loyalty to the Stag Lord and the other bandits, at least not when giving up information can help them.

As for giving them too much info to the point that it makes the fight easy? I'm not sure that's really a problem honestly. PC's should be rewarded for trying to use diplomacy, bluff, intimidate, etc. in order to extract information. I mean, obviously I would require some rolls along these lines, but you get the idea. For the most part, this won't be too huge a problem for the campaign as a whole, even if it does create a "problem" with regard to Book One. Additionally, this can yield some useful tools for the GM/party for later in the campaign. If things start to get dicey in their kingdom and the PCs start ruling with an iron fist, then you might have an even bigger amount of unrest. After all, "we thought you lot were just rulers, not more of the same power hungry glorified bandits that came before!"

I would consider rewarding your party's capture vs killing during kingdom building instead of the assault on the bandit fort. Perhaps have the church of Abadar (lawful) give them a free temple or a few helpful NPC experts migrate down to the new "honorable kingdom being established to the south".

There are very few preset difficult fights in Kingmaker, so you want to be careful not to make them too easy.
