Unlike some arrogant self righteousness I see in a response (but thanks for honesty so we know what one is made of), I feel that you are on point for addressing condolences up front. Hearts were broken, someones world will never be the same. That's putting it lightly. Same time- awareness has value..of how far- and how much destruction that the abandon of self and self control is capable of of doing- to what's really sacred, and which is just taken for granted.
