The path of my parents, the Gra, Musar, and Rav Shach.

Our beliefs about morality are guided by the social group we want to fit into, the self-image we want to maintain, the desire to avoid admitting to having been wrong in the past, and so on. It is pure accident if we actually form correct beliefs. An analogy: suppose you go to the doctor, complaining of an illness. The doctor picks a medical procedure to perform on you from a hat. You would be lucky if the procedure didn’t worsen your condition.
