Deliberately assumming a position in which you act and bet (yes, bet) with other people's money and in which you assume NO RESPONSIBILITY is an unjust position

Deliberately assumming a position in which you act and bet (yes, bet) with other people's money and in which you assume NO RESPONSIBILITY is an unjust position which you accept deliberately. Yes, it is hard to say but no, you cannot behave unjustly even if other people want you to. You cannot get a slave even if the other person wants you to get him as a slave. You cannot harm an inocent person even if he wants you to. The problem with Lehman was, essentially, that of lack of responsibility. And this is inherently unjust. So: with the letter of the law, they "do not need to go to jail" (say Lehman's board of directors), but with a reasonable understanding of justice, they acted in an unjust way. Wittingly.
