In our Ethics course, our professor ask us about "how do you make sure your feelings are morally mature and not trapped in the pre-conventional stage?"
Our feelings are morally nature and not trapped in the pre-conventional stage of we can make a decision without putting our feelings and emotion in it. Sometimes, we tend to make a rough decision because of what we feel.
We make this decision either because we are angry or sad. Being morally mature is about setting aside your feelings and emotion in making a quite hard decision not basing on what you feel or what the authority tells you to do.
Your feelings are morally mature and not trapped in the pre-conventional stage if we know the intensity of our feelings, we know who are involved, and we as well as know the consequences behind the decision we will make without putting our feelings in it.
Our decision should and must have justification and not biases. You must not decision depending on your emotion and feelings, because it may tampered the real and ethicsl decision you've really wanted to choose.
Be wise all the time. In all aspect, set aside your feelings.
