If you read any legal opinions in visible cases they are never just the judge feeling or not feeling sorry for the plaintiff (or defendant) and are deeply steeped in the law as written as well as precedent before even approaching making new precedent. Maybe a judge could comment but I’d venture they would almost avoid territory that would be ripe for appeal as much as possible.
Judges that aren't on specialized tribunals aren't expected to, and mostly don't, know the law (because it's quite impossible) - they rely on the Barristers to inform them, then get their clerks to do some digging to see if the briefs are on point. The higher up you go in the chain, the more clerk time they have to research and the more control they have over how long they take to put out their ruling.
Junior judges are more reticent to rock the boat - they have less resources, less understanding of how the judicial boards and other oversight mechanisms work, etc. Old greybeards generally stop caring - either about bothering to change things or about how 'safe' their ruling will be on appeal. The most active in tossing bad precedent out the window generally end up being the ones that get appointed to higher ranking courts.
