I think right and wrong depends on context especially because we live in a non-ideal society. It is a moral dilemma to decide how to act if we know we can't have what we need by rightful-legal way.
For example there is this famous question: There is an expensive medicine that will save one's life, you can't afford, will you steal it?
I have been looking for some key-words like subjective morality, relativism but I think it's not really what I am looking for. I don't look for a situation that is right for someone and wrong for another. I want to find an analysis or examples or opinions about situations where there is impossible to decide who is right or who is wrong. Or everyone is right yet outcome is a disaster.
Is there any person or book focused on this topic?
edit: deciding "it is impossible to tell the act is wrong and right is still subjective so my expression is not entirely correct. I just wanted to highlight that it is not what I want to find. I am looking for combination of different hardships which creates different morality than the standard approach, if it makes any sense.
