(I work with lawyers, but I am not one.)
It’s true that a major part of being in law is setting your personal feelings aside, but you also need to use critical thinking through the scope of professional ethics to represent the best interests of your client.
The issue that I see others in the profession having isn’t with the client of the case, it’s with the case and argument(s) themselves.
The lawyer is wasting the court’s time with indefensible arguments, which is likely to end up harming the clients not only in this case, but in their upcoming criminal cases as well.
