I get what you are saying. Personally, I think that it goes to character in terms of the affairs and delinquent child support. If he slacks off there, it is not that hard to believe that he might slack off in his professional life also; both takes arrogance to do.
However, I see the judge's point also. This is about Murray's level of care. In the end, it doesn't matter why he took the job based on the charges filed. His actions or lack of actions are what will be the deciding factors. I think that he is going to have a hard time proving he gave adequate care. That is why he is so desperate to make the trial about Michael versus himself. That is why the judge's decision that the trial has to stay focused on his care of his patient is most worrisome to his defense, I would think.
Actually, in the long run, would the money woes of Murray being brandished actually help Murray. Would jurors think that there is no way that he would risk losing that money (salary) by being so reckless in the actually care (not necessarily talking about the judgment to use it in the first place). In the end, it won't matter why he did it. It will just matter that he did it in the first place. Think about people charged with IVM because of DUI; people aren't concerned with why someone got drunk and drove but just that they did it at all.
