This line of argument appears to ignore the morality of acting rationally. No matter how repugnant its actions appear to be, UHC is acting rationally when it squeezes more profit from people. It is even acting rationally when it denies claims fraudulently knowing that the penalty is less than the profit. Calling it immoral when they don't do the 'right thing' is the real problem. Think of this from another direction, do we want a company trying to define what actions are 'right' and 'wrong' and then follow them? Because that is what we are doing when we argue that they shouldn't take every possible step to make a dollar. A company's only incentive is profit so allowing them to change the rules in their favor is the only irrational, and therefore immoral, action that has been made, and that action was taken by society, not UHC. We should assume that any company will, and should, take the most profitable move. Asking that they make any other move is to ask them to act irrationally and that is immoral. In short, I argue it is moral to act rationally, that society sets the framework for commerce and and that it is irrational, and therefore immoral, that we give them any voice or influence and further that it is irrational and immoral to have delegated the definition of what are 'good' or 'bad' actions to companies. That means that the only real argument that UHC is immoral is that they, or any company, makes an effort to change the rules or guide legislation. Or put even more bluntly, society is to blame here, not UHC, so any argument that violence against UHC by an individual is justified is misplaced.
