Classical Torah Theory is I believe a good system. I think it is clear that Classical Torah theory of people like Maimonides and Saadia Geon is advocating a morality that is logical, objective and humane.
This is however very different from Chareidi Jewish ethics of the modern era.
These two systems are so different it is not like comparing apples and oranges.

And I think the doctrine people believe in has a great influence on their actions

On the other hand I see Classical Torah theory as highly moral.

In response to this I recommend a return to learning Classical Torah Theory--starting with the Guide of The Rambam and the Emunot and Deot of Saadia Geon.
And when we find that our attitudes are different from those of the Rambam or Saadia Geon I suggest that the mistaken attitudes should be the ones to go.
