Yes but there where social standards however.
But they only count if people would know you broke them
You can still stab another noble in the back, while praying, in the middle of a church as long as it doesn't go public that you did it.
Alot of motiviation of a nobleman could be religious, but that probably means some priest is using him.
The few that are truly 'good' are too naieve and fall in the hands of a charming manipulator.
what i see is that deception has become overly prevalent way of conducting politics, and game mechanics was set in the way that it is not punished in any way, which in my opinion disturbs main storyline of bm.breaking social norms does, you lose ALOT of prestige when people find out your a back stabber, a torutrer or even executioner of nobles.
Vulgar behavior also gets punished.
What more would we need?
