GWB is about as poor an example of a sociopath as you can muster. There are quite a few documented cases of impromptu empathy.
You can hate the machine, you can hate the politics, but don't hate the person. It narrows your mind and cheapens your thoughts.
Bill Clinton is a little closer (as in harder to find impromptu, unexpected empathetic responses), but that's because he polished himself up earlier and better.
Yes, I realize it's a spectrum. I also realize that there are jobs where you are required to shed empathy in the role, or at least a large portion of it. Any job where you hold fiduciary responsibility, for instance, as it may be proven that you didn't act in the best interests of the stakeholders and might be held liable. At that point, you have to ask "What is the exposure?" of a decision.
Another excellent example, military leaders: The reduce their feelings to win tactically, or strategically... but I've known a lot of battle tested Marines, none of whom was a sociopath. In fact, when the boots and utes come off... I swear to god you couldn't find a bigger bunch of shit talking softies....
