I see some members of the community thinks the same as I. In RP ways, I think that it is a lot of metagaming killing a freeman because you do not like his family for any reason, freemans and commoners in general are not known by their surname but for his name and I think that is Power-Gaming to kill him because "I had a bad day" Judges have awareness and they are usually prudent in their actions.
Even though, if you are going to kill somebody, in all RPG you have to have a reason if he/she is a NPC and more if is a player. Obviously, chaotic people does not have to had a reason, and for tyrants is a sport. If you win the Freeman achievement I think that, since there and for the future, the people is knowing you (if not, there is not any reason to earn prestige and honour for an adventurer) more the time passes earning honour and prestige more the people will know you as the 'hero of the commoners' or something like that, and if commoners know you well, it would not be weird that if that freeman get executed (and more if there is no reason) it causes some civil unrest and honour lost (prestige might, but honour at list)
Am I wrong?
