A drug addict might steal from his grandmother to buy meth, but he'd feel bad about it. A sociopath would do the same thing without any emotion at all. A psychopath would steal and feel good about having done it.
what if you feel good when a clerk wrongly gives you more change than is owed? do you have to feel good about screwing someone over by your own intentions and efforts to be a psychopath, or is the consequence what matters?
This is a really interesting question in its own right, away from the 'psychopath'/'sociopath' question. I hypothesise that while a very low percentage of people would reach into an unwatched till and take money, a far higher percentage of people would happily walk away with too much change - presumably rationalised away by thinking that it's not your actions that led to the theft, but the mistake of someone else.
If the amount of money was what I think might be a large enough sum that would cause the clerk to get written-up, there is no way I would keep it.
If I got home and found out it was $0.50, I would probably rationalize it as ----- the clerk won't get in trouble for losing $0.50 & if they've done this over and over and over again ----- so that all the mistakes really add up, they need to get a different job.
If I got home (and the distance was pretty far) and I found out it was a large sum of money (not sure how this could happen--- maybe I was really tired), I would be very conflicted. Should I drive 50 miles so that maybe the clerk won't get in trouble? Even if I do drive 50 miles back to the store, the clerk's shift might be done? Do I remember the clerk's name.....maybe I could call the store and ask for him/her?
In any case, I would not feel good about the situation.
I, unfortunately, have some experience with addicts.
SOME blame other people around themselves for all their problems: "If my wife wasn't such a horrible person, I would not need to do all these drugs. I need to rob that guy to get drug money. But it's my horrible wife's fault that I'm an addict. If I wasn't married to her, I would not need drugs. I can't get a divorce, because it would not be good for the kids. See, it's all my wife's fault." (Boss can be substituted for wife & job for kids...etc)
I'm not sure if that kind of thinking would constitute psychopathy or not? And even if it would, then wouldn't the psychopathy be, at least in part, caused by the addiction?
