I want to take over the village and get it's valuables, and something very specific.
A Masterwork Mail Haubergeon.
I agree with PALU, other than ethics (which is yours to ignore), I would advise against it simply because it is not worth the effort (time & riskwise) and of course there already is a clearly better way of obtaining all those items (hint: active hunt elks/reindeers & trade).
If you try this, most likely outcome is you will die.
Having said that, if you are really determined to murder for profit, probably best to do it a few or even ideally single human at a time. Similar to animal hunting tactics, try and circle the village, ideally at night time, to pick individuals, let them chase you way outside the village.
Note that you will not always manage to separate one human away - many times they will start yelling like crazy, bringing along the half or entire village (I know because a friend of mine did this also). It is best to disengage in those circumstances because even kids in this game are Terminator T1000s that have no hunger/self-preservation; they will keep at it forever until you are down. Due to the way combat system works 2 kids and an adult can kill you in most attempts. (Needless to say, a village typically has much more population than 3).
To reduce risk, try to tire the individual you picked away from the village first, only then kill them. Rest, repeat. Don't rush.
Having a shield and some skill with shields can make life easier. Note that to gain skill in shields, you can do what was suggested to you earlier in another thread: buy one or ideally more shields and throw them on the ground (a neighbouring tile next to your feet) all day long. Eventually you will gain skill points.
Again, I agree with PALU. Don't do this. And remember to share the outcome of your very risky attempts.
