@Sentience,
Well, if we're talking about jails, how many of those sorts of thieves do you think there really are? I think there are many more who say "Oooh I want that, I can't afford it, oh well I'll get it anyway... by stealing it!" or variations thereof. No altruism involved.
A corrupt businessman would be
another example of someone knowingly doing something wrong, but there are plenty of thieves who are knowingly doing something wrong and who don't have any particular extenuating circumstances.
