It looks like these programs were initiated under the CEO that was shot, and have continued under the new leadership. So, I doubt prosecution would matter much: Even if the courts somehow decided to levy murder charges + seek the death penalty, that wouldn't be enough a deterrent for UnitedHealth's leadership. At this point, it looks like criminal murder charges (seeking the death penalty) + federalizing the company would be minimal next steps towards fixing the problem. Of course, that won't happen under the current administration.
