Disillusionment
I tend to think of logic as the most versatile tool to solve moral dilemmas. It disentangles the complex web of moralities to fundamental concepts of logical and illogical. However, occasionally, there have been situations, where I have not felt comfortable with the solutions that I found; even though I could firmly support those solutions with logic. Perhaps what the best known icon of logic said in "Amok time" applies to these cases, and the solution though "illogical is often true".
