It really does not matter (You are making a decision upon your beliefs of the Golden Rule) - you can NOT make those moral decisions on your own, otherwise we have a wild mix of decisions made by different people depending upon their own beliefs, yes? That is ultimately why moral decisions have to depend upon higher authority...
The Golden Rule strongly tends to influence judgment towards the direction of altruistic behaviour, without providing much room for ambiguity. To that end, decisions made by applying the rule will not be too varied, if at all.
