I guess I really am deplorable because I can't even begin to understand why what he said is wrong. If one or more of my wife or kids was in the car with me and I felt they were in significant danger from violent rioters, I would do anything I could to get them to safety and if that involved running down 1 or 10 or even 1 million rioters to do so, I wouldn't hesitate and I wouldn't feel guilty afterwards even as I spent the rest of my life in jail or ended up in the electric chair for doing so. And I can't begin to imagine why any other husband and father wouldn't do the exact same thing.
If it was just me in the car? I don't know. I'm not sure my own safety would motivate me to run anybody down just to save my own skin.
One of the interesting issues with the Trolley Problem and other related problems is the following:
Greene and Cohen analyzed subjects' responses to the morality of responses in both the trolley problem involving a switch, and a footbridge scenario analogous to the fat man variation of the trolley problem. Their hypothesis suggested that encountering such conflicts evokes both a strong emotional response and a reasoned cognitive response, and that these two responses tend to oppose one another.My experience and knowledge tell me that in the heat of the moment, the "strong emotional response" usually wins. The emotional response affects the lower mammalian/reptilian brain and that part of the brain is between the cognitive part of our brains and motor control and the lower brain can completely lock out the upper brain if it so "chooses" under strong emotional stimulus. It's instinctual and reactive and when a split second decision needs to be made it makes it and not always in agreement with what the cognitive portion of the brain would choose if it had more time.
The Trolley Problem and its variant are usually applied to strangers. I'd like to switch it around a little. The trolley is headed for your child or spouse tied to the tracks and you have an instant to decide whether or not to pull a lever to divert the trolley where it will instead run over 1 stranger who is tied the tracks. Or 5 strangers. Or 1 billion strangers. What if you and your spouse or child happened to discuss this ahead of time and they said that they would feel so guilty about the strangers' deaths that they wouldn't want you to pull the lever to save them? In each case, you have 1 second to react.
I don't think you can know the answers to any of those questions. Sure, you can cognitively think about them and know what you would logically decide. But, in the heat of the moment, your logical brain isn't the one to make the decision. I think that a lot humans, possibly myself included, in the heat of the moment, would end up pulling the lever and saving our child or spouse in all of the above cases.
I believe that our lower, primitive brains are actually always in control or at least exert a constant pressure and that the cognitive brain that we consider to be "us" is mostly just a tool used by the primitive brain. Some of the whispering pressure from the primitive brain is obvious: eat, mate, etc.
But some of the whispering pressure is more subtle and hardly even noticeable but has a profound effect on behavior. It sorts people by importance and makes even your cognitive brain react differently to the Trolley Problem when the people are known to you and at different levels of importance. For example, instead of strangers, it's your mother, or cousin, or friend, or important colleague, etc. And it's not just how you react in the heat of the moment, but how you provide for some, criticize others, cut yet others slack, hire others who really aren't the best objective choice, etc.
One Libertarian question is what's really the difference between trading with one of your countrymen and trading with someone in China. Objectively, there may be little difference. However, our lower brains may simply view strangers in China as less important than strangers in our own nation. We can say that's an immoral view, but if that's innate, and I think it is, at least for many people, we're really just saying that (many) humans are innately immoral.
