In my eyes, you are! In the classical definition, you will at least have to answer/be held accountable for all of that by your later self. Other people invoke external judges but the internal one is typically the toughest of all.

Then again, you seem to see it something negative (guilt/blame perhaps), whereas I see it as something that makes me aware of my power, my total sphere of potential influence on the world, and the inherent value of my actions and my existence. To me it is empowering. And for me it’s not about selflessness either, but the opposite. I am responsible to make the best out of my situation, based purely on my own values. It doesn’t get more selfish than that. And again, this is not some moral preaching to me, but simply stating the obvious: Nobody but me is responsible for how I act and how I set my priorities.
