" Is it really so difficult to tell a good action from a bad one? I think one usually knows right away or a moment afterward, in a horrid flash of regret. "
- Mary McCarthy

This quote reflects on the inherent human capacity to discern between actions that are morally right or wrong. The speaker suggests that people often have an immediate sense of whether a deed they've committed was good or bad, which can be instantly recognized either during its execution or shortly after. This intuition is marked by feelings of satisfaction for positive choices and regret for negative ones.

The deeper meaning of the quote delves into the complexities of human morality and conscience. It implies that ethical judgment isn't always a matter of complex deliberation but rather an intuitive response rooted in personal values and societal norms. The momentary pang of guilt or remorse following a poor decision highlights how our subconscious often quickly evaluates actions based on moral standards, even if we might try to justify them rationally afterwards. This insight underscores the importance of listening to one's conscience and acting with integrity.
