It's almost like the real world just doesn't deal in absolutes. For any absolute blanket rule you'd like to apply to the entire universe, there's a practically infinite number of exceptions and edge cases.

The real world is subjective and messy. Life is an endless series of edge cases and unique situations. The real world also has no requirement to be logically consistent or in any way rational. Every rule has exceptions, no set of rules and codes can cover every situation.

The nature of life is that your personal moral code will break down at some point. Your personal sense of right and wrong is not a universal truth, and you will be faced with situations that challenge your morals.

A wise person understands this fact, and a mature person can handle the messy reality of morals. An immature person thinks their personal moral code is universal truth and must never be questioned.

My morals tend toward Buddhist views, but I've been around long enough to learn the compromises that reality requires. Violence must always be avoided at all costs, but sometimes it is necessary. Occasionally violence is good. There are no hard rules, reality just plain and simple does not work like that.
