What makes our morals correct in analyzing literature? Do we have the right to judge characters?

This question is particulary important to me, becuase I struggle with the answer every day. Too often, humans judge there actions simply because it feels right or wrong. I think that there should be a balance of feeling that an action is right and knowing that an action is right. I began asking myself this question before I can remember, because I have consistantly be disposed to question the moral standards placed upon me by others as well as myself. To me, all morals should and can be realistically theorized and proved. In my life, I consistantly search every value I have to ensure that it is the value that makes the most sense. The justification for these values comes in varying complexity. Take drinking and drugs for example, I know that I would rather be satisfied with who I am than momentarily happy with a physical sensation. The effects of both substances are simply ones that make no rational sense: loss of vision, loss of self control, loss of awareness, loss of meaning in life, addiction, and lost of self respect. Other, more difficult justifications come in the form of much simpler things, the small things we do in life. And the most difficult questions are that of the function of societies in this world, which I believe are almost always morally off course. I do not hide this question, I believe all actions deserve a justification.
