Ethics
From RationalWiki
Ethics is the branch of philosophy that explores and lays out the proper way to live. Most ethics are concerned with how people should treat each other. The most generally agreed upon statement of ethics is some variation of "Treat others like you'd like to be treated." Beyond this, however, ethical systems can differ sharply, depending on other axioms. For instance, from a Christian perspective it may be permissible (or even necessary) to force someone to convert to Christianity, in order for them to avoid Hell, whereas in most atheistic ethical systems that is a gross infringement on the other person.
One concept which blurs ethics from the cut and dry, black and white world Christians pretend it is into a big gray goo is moral luck. A drunk driver may safely reach home without injuring anyone, or he might accidentally kill a child who runs out into the street while he is driving home. How bad the action of driving while drunk is in that case depends on chance.
