Everyone is the hero in their own story. Few people actually gleefully play the scoundrel. The ability humans have to self-rationalize is amazing. And even when folks are doing something they know is wrong, often it gets justified in the balance: the victim deserved it, the perpetrator is Robin Hood and proceeds will benefit those who need it more, the action makes up for a historic injustice, etc ...

I doubt it. Every time there's an article on here about the latest outrage from $FaceGoogzon there's no shortage of well-paid rationalisers in the comments. I'd expect the same is true of the RIAA. Especially among their legal team: there are far more unseemly clients than the RIAA out there.
