The easiest power to abuse is power nobody expects you to explain.

Unexamined authority is the most easily misused, not because those holding it are worse but because nothing prompts them to check. Where no one asks for reasons, decisions stop needing to be defensible, and standards drift without anyone deciding to lower them. Explanation is a discipline as much as a courtesy.

Where you hold authority that nobody questions, explain a decision anyway, out loud, to someone. Having to say the reason is what keeps the reason honest.
