The problem I have with obligation is that it is tied by definition to legal and moral definitions. I myself do not see obligation in that light per-se. If someones says they are going to do something are they then obligated by moral code to do it, or by legal code to do it. Many would say yes cut and dried he/she said they were going to do this and they did not, therefore they are not a moral nor just person.

It matters not in the minds of the people casting judgement, but life happens things change, and obligations need to be reworked. All they (those who judge) see is that they made a choice to do something, they committed to doing something, and for whatever reason they did not keep their obligation, so they are wrong.

I do not think people are obligated to anyone other than themselves to fulfill an obligation. Casting societies moral and legal codes to all peoples even those outside of your community is wrong. It is another tool created to control fools.
