Is utilitarian moral judgment hosted by the prefrontal cortex?

This now post no. 3 in a rather short time period about location of a behavioural trait to a certain brain region [1, 2]. As someone who is more influenced by deontological ethics, I find it funny that the authors describe utilitarian judgments as result of brain damage… The six patients they have been testing had markedly reduced social emotions (compassion, shame, guilt) as well as poorly regulated anger and frustration tolerance – while having a normal general intelligence and capacity for logical reasoning. Yea, yea.

The Allen brain atlas of genes expressed in the cortex has a joke on dickkopf=bullhead
