Sacrifice ? What a nonsense. Ruin the mtgox, do what ever you want with them , but that rollback was done right. Nobody asked Kavin to give back that 600  BTC, well - that is not true, i am asking.  At least nobody demand it. I am not concerned about mtgox future, let mtgox burn in hell. But what mtgox doing right now is absolutely legit. I am looked at this from complete different sides of view, and do not find any flaw in their position on rollback. I am do not care about mtgox, but  compared to mtgox and bitcoins, that Kavin just not exist in my opinion. Well not exist until he can prove that he suffered losses in that force major. And as i see - he did not.
