I wrote this a couple days ago but I never bothered to post it because I didn't think it was complete. Also, these are my thoughts on the subject. My conclusions give me feelings of sadness, anger and apathy.
Rightness or wrongness aren't concepts that humans are able to understand...but we are still driven to try to. We inevitably fail. I would argue what most people think of as "right" is really just "consistent" within a model that they have chosen to be the standard. There is very little conflict when the standard system is based off of universal perceptions (hence science) but when a model is based off of personal experience or opinion then a lot of conflict tends to occur.
I think that there are 3 types of rightness/wrongness.
a) Rightness/Wrongness that is in fact right/wrong. This level is not accessible to humans. We try (through science, religion etc) to achieve this level..but to my knowledge not one person has ever succeeded. ( I would argue that achieving this level is synonymous with things like finding god or your purpose in life..)
b) Rightness/Wrongness that is based on universal perception or universally agreed upon truths. This level is what most people think is the first level of rightness and recently it has become the standard level of judging rightness or wrongness (think why the sky is blue, or why 1+1=2) these truths are simply defined truths that we have all agreed upon. We can then work from this framework to and find out more truths within the system.
c) Rightness/Wrongness that is based upon personal experience (perceptions). This level is right/wrong for the individual. Conflict tends to arise when a significant amount of people have the same experience. This level tries to force itself to go up one level where it doesn't belong. Think (democracy, religion, etc).
