What I'm curious about is why the DM allowed him to play an evil character in the first place. That almost never ends well.

Never, in the history of any of my games, has a chaotic evil character been anything but a detriment to the enjoyment of everyone in the party.

I'm not saying it's not possible, but there's a particular kind of person who wants to ruin other people's fun, on purpose. The group is understandably upset, and I would blame the player for thinking that such an action was a good idea to begin with. The DM is also partly at fault for not establishing ground rules and "party etiquette."

It takes a real "pro" player AND experienced DM to pull that off.

I heard a story about such a session where everyone was pissed off, but had fun all the same.

It's very hard to find balance. The right amount of evil at the right time. Stabbing everyone in the back during a boss fight would not fly.
