Yikes. I agree with the employment attorney idea and I think HR would help here. There are other options, but they're risky and you shouldn't have to do this in the first place.

Who do you report to in the structure? What's the culture elsewhere in the company? If the culture is positive elsewhere and upper management seem like decent people, I'd go over your manager's head and explain what's going on to an executive. This sounds like a bad manager scared to have a difficult conversation. Outline specific events, with dates and relevant people, then put it in business terms. Employee retention, work quality, motivation as it relates to deadlines/innovation, etc. Whatever personal perspective you want to add, I'd keep it in a separate section because if they care, it'll be obvious what the impact to you is and if they don't care, they can focus on the business cost.

I guess if you're feeling really empathetic, you could talk with the abusive coworker directly, but that's a risk. Even just trying to connect with him as a person - asking him how he's doing or something non-work related.

I'm sorry you're going through this and I hope you find a way out. If it was me, I'd tell the boss that I won't work with $abuser and to go fuck himself if that's a problem. Apparently that kind of behavior flies.

Any move one can make in this situation entails risk, unless losing the job itself is not an issue.

Losing my job would very much be an issue. It's just unfortunate that he has been getting away with this kind of behavior for so long precisely because reporting him is fraught with peril and people have just allowed him to continue without saying anything.
