Bernie Madoff is a jerk, and he's greedy. It looks like 10 of his closest friends and relatives will be going to jail with him. However, I don't understand the "excessively evil" part.
Madoff took people's money. That's it. He didn't kill, he didn't threaten, he didn't even extort. People who were greedy for "guaranteed results" flocked to give him money when they should have known he was crooked.
I'm sorry that a lot of innocent people lost their life's savings. If it is your life's savings, you shouldn't have every cent of it with one person anyway.
Bernie's old; any sentence worthy of his crime would be a life sentence. I just can't see the glee at 150 years when murderers get less.
