The modular theory of brain function has given way to a more nuanced understanding. Some functions are very localized, while others are quite variable between individuals. Functional localization depends on many factors, such as the wiring of afferent and efferent neural tracts, gene expression, and plasticity. For some functions, this strictly constrains the location, for others it doesn't. But, the point is that it doesn't matter if it seems absurd to you that something "high-level" like morality is localized. The evidence says it is.
