I do it every day, but it's not easy. From time to time, I'm tempted to mix the two, but that's not allowed. We always need to be mindful of that.
As a judge, I rendered a number of judgments and I had to think about the impact my personal views might or might not have. I don't believe they got in the way. When a judge is faced with that, they ask for a colleague's opinion. They can read the colleague's judgment and ask for their personal opinion as to whether everything's been done right or whether something is questionable. After a while, it becomes automatic. You leave all your personal views at the door to focus on what's in front of you.
