The people who cause most of the grief in this world are rarely held accountable. Especially held accountable in any justifiable and equitable way. That's life, basically. The basic tenet is true: life isn't fair.
When those times happen, as has always happened throughout history, a population of people who largely may not be the cause have to come to the rescue and be part of the solution for the problems that have befallen them. Even more unfair, some of the people who have to pay the burden are the very people who were saying, "Don't do this... this will end badly" when nobody listened. "I told you so" has even less meaning for them.
Which isn't to say that the IMF/EU is doing enough to focus on salvaging the society and not just the debt to creditors -- as was done for post-Weimar, post-Hilter Germany. But the fact they even lent any money at all to such an economically unsustainable nation to begin with borders on charity. Like lending money to your derelict cousin who is about to be evicted from his apartment, even if you know he's mostly going to spend it on alcohol and women.
