I’m puzzled that people are disagreeing with Jacoby’s conclusions. If Mr. Bulger were “hard-wired,” then he had no personal agency in has actions, and he bears no personal guilt.

There is evidence that psychopaths are born, not made. They really do not have the capacity to empathize with other people. They have no remorse, they feel no guilt. Brain scans show that they are missing the "empathy" regions of their brains.

That said, it is not a foregone conclusion that psychopaths are murderers. To a large degree, how they are socialized as children determines how they behave later on.

True. And they tend to partner with each other.
