To interpret words, as a judge does, is inherently biased.
Just because two people disagree on an interpretation of law does not mean they are not applying that law in good faith - we all have worldviews and beliefs that naturally color our understanding of reality - which includes our understanding of laws.
We attempt to write laws clearly to avoid personal interpretation, but it's impossible to avoid all interpretation. Thus we appoint wise judges to do so for society. Even wise judges have unique worldviews.
