I don't know, if you hear about the accounts of the parents of children killed in Sandy Hook, I don't think inner peace was available. Many had to move or go into hiding. Imagine, after losing a child in such a horrific way, that you also need to somehow start an entirely new life in a strange place because strangers think you're a crisis actor and threaten your life.
I think it's extremely hard to come to terms with what happened and be happy, if what happened (or rather, what is happening) is "I'm currently being chased out of my own home because people online want me dead because my child was gunned down in a domestic terrorist attack".
Externalities matter.
