For new players who wander if its possible to make a full no crime run (I have not yet found anything that clarifies everything), I think is possible but you have to give up on certain things.
- “Ruin” side quest. For its considered looting to grab the spurs and the ears.
- Killing Black Peter. For he is considered a civilian.
…I will update on more things. I am being very careful in my run, so if there is someone out there who wants the same, it might help.
