No, not the General Public License, that's a different kind of moral licensing.
http://en.wikipedia.org/wiki/Moral_licensingRather, the way that doing occasional good deeds makes people feel free to do bad ones in compensation. I've seen this pattern in my own thinking and behavior fairly often, to the point that I have my own term for it; but for some reason it didn't occur to me that psychologists might have one already. Anyway I'm glad I now have a "legitimate" term to keep in mind.
On some related notes:
- IIRC some serial killers show an extreme example of this. "I'm a pillar of the community, I've helped so many people; what's a few murders to that?"
- The most morally stringent people I've met have all had a cruel streak... Working in soup kitchens and women's shelters, having work ethics to put me utterly to shame, saving the lives of strangers and all but destroying themselves for their ideals; and yet always willing to hurt those around them on the small scale. I wonder if that's related, in some weird inverse way.
