The Perennial Power of Envy

I'm currently meandering my way through Josephus' Jewish Wars (or The Judaean War); Having narrated about Aristobolus becoming the first High Priest to also declare himself King (by putting a 'diadem' on his head) and his resoluteness to maintain such a status (by arranging for the possible assassination of his brother, Antigonus--who, despite deep mutual affection, Aristobolus suspected of plotting to take control of his Kingdom), Josephus says the following:

...[B]ut [Antigonus] was slain by the body guards, and became an eminent instance how calumny destroys all good-will and natural affection, and how none of our good affections are strong enough to resist envy perpetually. Wars 1.3.4
