noun
immoral and thoughtless behavior; outrageous misconduct
Formal or literary term for behavior that is both morally wrong and reckless, often implying a lack of reason or restraint. Rare in everyday speech.

The politician's outrageous misconduct drew widespread criticism.
歴史書には、暴君の狂悖が克明に記されている。

The exact derivation is uncertain. The kanji 狂 (crazy, wild) and 悖 (rebellious, contrary) combine to suggest behavior that defies reason and morality.
