Question

Can culture be used to justify democracy is athens

Answer 1

If I understood your question correctly, the culture that was present in Athens at the time when they first started with the project we today know as democracy surely did play a role in the atual development of democracy. They did not have a central authoritarian figure which would ruthlesly and without question rule over his people as was happening in other place, this was one important reason for why democracy could have been developed there in the first place.
