While I am not defending MtGox, having your entire life savings wrapped up in Bitcoin is hardly a sound, proven financial decision and evokes absolutely zero sympathy whatsoever. Losing it all in a get-rich-quick frenzy is sad - but it's sad in a "I can't believe people are willing to bet their lives on this" way, not a "this poor person lost his/her entire life savings due to the corruption of the financial industry" way.
Putting 5-10% of your net worth in something like this is being innovative and forward thinking and taking a calculated risk.
Putting 90-95% of your net worth in something like this is serious, foolhardy gambling.
Besides, the way their money is lost made it so much worse. The global value of btc crashing would be one thing, corruption would be another, but this level of incompetence.. it's almost harder to digest since they most likely are not guilty of any crimes either, unless stupidity would be a crime.
On the other hand, if we think about the coping strategy for people who've been Goxed, I can see where if you can disregard the winnings as "paper gains" it is much easier to get on with life thinking "I only lost 10k."
