That’s not right. Negligence doesn’t have to be accidental, it just means neglect. That can be a neglect of responsibilities or a duty that you willfully choose to ignore. None of that has anything to do with this situation, but you’re wrong about your interpretation of the words and willfull negligence absolutely is a thing. A parent that sits and watches TV or plays video games while their kid is screaming in the next room(about something that requires adult intervention) is making an active and willful choice to neglect their child. Or oil companies that were aware of the consequences of carbon emissions and chose not to action any action except to deceive the public about it.
