There was a concept of justice, if the pre-socratics are to be believed (and if their view reflected the earlier views - which I conjecture it did). Thrasymachus (the Sophist) gives his understanding of justice and injustice as "justice is what is advantageous to the stronger, while injustice is to one's own profit and advantage". So you are right in saying that "the strong took everything from the weak justly by virtue of their strength" but this was seen as justice being done (the weak having no right to do anything about it. Might makes right, the law of the jungle, pre-Axial Age justice.
