Are stock market & financial institutions 'evil'?

What do you all think, especially with the current evident global financial crisis, and people are losing faith in the often-revered capitalism system. Moreover, the jobless/unemployment rate is increasing everywhere, and many people are killing themselves now because they can no longer understand/grasp what “Life” really is anymore.

So my questions are as follow:
Did the stock market & financial institutions really ‘steal’ the money from the multitude of poors, only to feed to the few riches?
or, is this not necessarily true? (ie: it’s not necessarily ‘evil’?)
Perhaps it does provide some good values somehow?

Please explain.
