I doubt the lawyer has his client's interests in mind all the time: A new trial with more money coming up, media exposure, "25 years is jail isn't that bad, could've been life," "if we wrap it up by Tuesday, I can still make for Jeff's birthday party" etc etc. Lawyers are human and representing clients is a business. The most important period in your life is just another trial to him.
Bottom line: Unless the lawyer is willing to do his client's time, he should be overruled by the person that really stands to lose, the client.
