even I realize that these trades must be rolled back in order to prevent a loss of confidence by the investor group.
mtgox will restore confidence and keep the bitcoin economy alive. It's a win-win.
I'll tell you what causes a loss of confidence: an exchange that takes arbitrary actions which it never specified in its user agreement to protect itself.
I got all of my dollars and bitcoins of of mtgox a few weeks ago. I've been generally unimpressed by the standard of mtgox software ever since it was first released, and this whole hacking fandango came as no surprise to me unfortunately.
With that said, MtGox does have some culpability.
What's with so many people loving mtgox? they have "some responsibility" for writing crappy software, getting hacked via a dodgy auditor and getting the entire contents of the exchange sold off in 5 minutes? You're right, they do have the tiniest smidgeon of responsibility there...
