Meta-Ethics

While normal ethics addresses such questions as "What should I do?", evaluating specific practices and principles of action, meta-ethics addresses questions such as "What is good?" and "How can we tell what is good from what is bad?". At its core it addresses the relativity of ethics (or moral relativism) which is the concept that something that is deemed good might not be good for everyone i.e. it is simply a matter of contextual framing.

Isn't Good or Evil, just a matter of perspective?
