Most of us do have moral opinions, ideas of what is right and what is wrong, how people should act and how they should not act, and of what kind of world we wish to live in. It is much preferable to act in accord with these beliefs than to do otherwise.
It is also true that all choices and all acts have consequences - even though many times these are not predictable and the connections are not direct or even traceable. I prefer our society to others I am familiar with so I try to act in accord with and support its pillars - those choices, rules, acts which I believe constitute its bedrock. I think others do the same. Since circumstances change one must adapt and its not easy to know how...but I do my best and I think many others do the same.
What more do you want?
But the people who committed what you and I would call heinous acts in service of their morality were acting in accord with their beliefs. So were they acting heinously or was it preferable to do what they did?

Indeed, and not just in America. Saudis who prevent women from driving are protecting the bedrock of their society as they see it, which is the society they prefer. Is this merely a difference of taste, like prefering techno over classic rock?
