Disciplines Personally speaking, I don't think there are any universal moral principles. Nearly all moral principles are/were set artificially. To set a principle is always for a purpose. If the result of the violation against the principle doesn't influence the realisation of the purpose, it isn't inevitably wrong. For legislative and some public principles, the process of the implement of the rules is as significant as the purposes of the corresponding rules, even more vital. Only this can make the principles to be obeyed fairly or equitably by every individual. While for some personal principles, particularly which have nothing to do with serious issues, (e.g. death, health,), I think the purpose is more important than weather others comply with the principle itself. Generally we respect others‘ personal principles, it is because: 1. we expect respect in turn; 2. there might be some potential consequences which others don't know or can't know. Despite this, we might still make some mistakes according to the principle-maker’s standard, because we don't know how strict we should obey it. However, I don't think this is a big problem since we can figure it out after more explanations and detailed descriptions from the maker.
