Well, you can decline a case if you think it's not possible for you to do a good job on it. Arguably this could include a hatred for someone. If the person negarively affected you or your family with the crime, then ethics may even dictate that you can't represent them.
Although I do agree this scenario of quitting a firm because the firm represented someone is a stark departure from these traditional exceptions. I get that people don't want to work for a company that does morally wrong stuff, but I don't think providing a defense should fit that. The whole concept of the system is that it should be a fair fight under the rules of law/procedure. It's almost like they're saying that they think the rules aren't fair, but that they would rather not afford people their due protection than try to correct the actual injustices in ehe system.
