If someone stole from you, say maybe $1000, you get over it. If someone made you make a jump and you fell and got a broken arm, you get over it. However, if a thief stole your (and uncountable others) house and life savings and this person is responsible for the death of uncountable lives AND yet this thief unfazed runs freely throughout the world to continue with their fraud and cost of uncountable lives, I will not get over it!
However, we must try, to develop ourselves with positives for our health, and a joy to share with our loved ones. I, too, have had to make an effort to not discuss anything about this "thief" with a family member who was once a JW.
