What separates us from the love of friends is envying or being envied, causing or receiving harm, insulting or being insulted, and suspicious thoughts.  Would that you had never done or experienced anything of this sort and in this way separated yourself from the love of a friend. –St. Maximos the Confessor (Fourth Century on Love no. 21)

 

The explosion of anger by someone when confronted with the evilness of their behavior which St. Maximos describes below is today considered symptomatic of predatory behavior.  When the predator is exposed, he goes on the attack hoping to intimidate the prey back into some more submissive behavior. –Fr. Ted, Disturbing the Predator

That is exactly what happened to me.
