The soldiers don't really worry me, but I can't kill them quietly. This should mean there is another hero here somewhere, I need to see them to decide if they need to die or not. There is also a chance the hero left his troops here and went to the main church to talk to the leaders.
My main question is why, the hero should be out searching for me, so why is he here? Maybe I will find out when I meet him, but for now I just need to slaughter everyone. The soldiers have sentries out around their camp, and the church has sentries around the village.
If I attack either group of sentries the odds are I will end up fighting everyone and the village might suffer in the battle. So instead I sneak past all the sentries and head for the church first. Killing the soldiers and priests is fairly easy, once I free the women they held captive I have them quietly gather the villagers.
