Nice! Brings to mind something I've been reading --

It is mutuality, not reciprocity, fellow-feeling, not calculation, which is both the motive and the reward for successful co-operation. And the outcome, in utilitarian terms, is not the important point: it is the process, the relationship, that matters. ~ Iain McGilchrist, The Master and His Emissary: The Divided Brain and the Making of the Western World

And in case anyone should think that empathy necessarily means being soft on others, those right-sided regions include the right caudate, an area known to be involved in altruistic punishment of defection. ibid
