I think 'responsibility' is a better word. We are 'responsible' for one another, but in far more than just 'caring' ways. We take out the trash, we try to get along, we do all sorts of things every day that really fall into the category of 'acting responsibly' that in some ways could be described as 'caring' in a more general sense, but it wouldn't be apt. 'Conscientiousness' could be an even better word.
