Roguey, let's take that concrete example that Grunker offered.
Might and Magic 7 allows character promotion to explicitly Evil classes: Liches, Black Knights, even a class called Villain. Clearly, if any adventurers would murder innocents, it would be these guys, yet non-encounter NPCs remain unkillable. Would you say that this is because the developers were simply "lazy"? Was this behavior out of scope for the kind of game they wanted to have? Or was there another reason?
I don't know but I have zero interest in playing M&M 7 on account of its ugly 3D graphics and awkward realtime/turnbased combat.
I do recall being able to murder townspeople to my heart's content during the few minutes I played M&M VI so it sounds like a downgrade to me.
You can in MM7 as well. But just like MM6 you can't murder shopkeepers and quest givers since they are not implemented as actual NPCs - they are 2D images in building screens.
