I think a lot of it is simply there's a lot of frustration that crimes like this go on every day. Many people see the top levels of finance as all being tainted by fraud, stealing from ordinary workers, and this acts as confirmation for that. Bernie's fraud imploding did motivate several suicides. Not exactly killing by his own hand, but he does bear some responsibility. We also shouldn't ignore he cravenly focused on charities as their legal requirements would give his ponzi scheme the longest runway. He also leveraged his reputation in the ultra wealthy NE Jewish community to find victims. So independent of the common outrage, I can see how a lot of people would see this as a particularly ugly betrayal.
