“At the time of a person’s anger, faith in G-d has left him.  For were he to believe that what happened to him was G-d’s doing, he would not be angry at all.  And while it is true that the person who is cursing him, or striking him, or causing damage to his property, possesses free choice, and is therefore guilty…nevertheless, as regards to the person harmed, this incident was already decreed in Heaven and G-d has many agents through whom He can act.” ~ Tanya, Igeres Hakodesh ch. 25
