I was going to try a low chaos run, but it just doesn't feel right. They should have made the soldiers seem like they're caught in the middle and just decent people trying to make a living for their families, but instead they're all seemingly rapists and murderes according to that heart thing.
It is something I wish games like this did better - give soldiers like that more variety in terms of character and more responses so the options aren't just to kill them necessarily and not always they just try to kill you on sight, etc. (plus there is always something extra satisfying about finding creative ways to off the bad ones after you've overheard some conversation where they are talking about their deeds or intentions, etc.).
