People often under estimate the challenge it is to identify a right action from a wrong action. Sure, many of us don't have to make that choice often consciously. But it's fun to think it out, and even understand so that few decisions we take sub consciously, we can start understanding them better.
To start with, you may think it's not really difficult but the more you think about it the more you would come to same conclusion that it is not in fact that easy.
Sure, killing someone is largely bad and charity is largely good but those are the extreme ends and many of us live our lives in the center.
Though there are several examples we can go into it, from deontological ethics to consequentialism to understand the depth and nuances of understanding right and wrong but that's for another day.
One of the problems I have noticed when it comes to community is that sometimes a community or a culture would outsource part of the morality. Outsourcing can be too a book, to a place, to an institution, or just sometimes to people in general. But anytime you do that you risk being a immoral in your own eyes. Sometimes society might ignore it on the surface but underneath the surface is where the hatred boils.
When Nazi soldiers put their morality and trust in the Nazi institution they ended up being considered one of the worst in humanity. Yet, we continue doing that, instead of questioning every act of violence we outsource our morality to someone else, for a soldier it is his country, he can do no wrong in killing enemy because his country and politician determined what was moral act. For a religious person it might be his/her religion. For an employee it might be his/her employer. This could have things which you don't agree to rationally but since you have outsourced your morality to it, you can do really terrible things and not repent it. It takes away Human's ability to empathize and puts that creative mind to torture more of it's kind.
Now, different people living in same place getting morality from different places are bound to have certain issues, because both consider certain things to be right and others not. Now comes the tricky part, if you wanted to inoculate yourself from this immorality one easy but not necessarily the best way to do it is take your morality from general prevailing notion and law of the land, in many cases this would be wrong but looking at different societies we might largely be able to be on right side of the line.
This does not however eliminate the problem, this just converges many different moral leanings into fewer ones. But we need to be aware of this bias that these are generally accepted moral rights and wrongs because they were common denominators and not because of any debated or accepted moral leaning.
May be it is true, there is no absolute morality only accepted morality.
