Moral Dilemma

What is a moral dilemma? A moral dilemma is a situation a solution maybe be morally wrong or unacceptable yet is the most preferable one. The fundamental nature of a moral dilemma is choosing between two or more opposing beliefs or values. One example of a moral dilemma that I can think of  in the real world can be: You are a dean and you have to select a student to give a scholarship to attend one of the colleges in the country for free. You have two possible candidates, one is arrogant, obnoxious and comes from a wealthy family yet attains the best grades. The other one is hardworking, patient and comes from a poor family that cant possibly achieve to get to the college using their own funds however his grades are much lower than student A. Who do you decide to choose?
Personally this is a difficult choice as the one that works hard with less wealth and grades requires this opportunity to get somewhere in life yet the one with the best grade surely deserves to achieve the best education. I would choose to pick the student that is wealthy, obnoxious and has the best grades as I think schools need to maintain the high standards. I chose the ethics of justice as the one with best grade deserves it while, if I chose the ethic of care, the poorer student deserves this opportunity.
