“Many of Grammer’s family and close friends were killed in violent or accidental manners. In 1968, his father, whom he had seen only twice since his parents’ divorce, was shot dead,[4] while in 1975, his younger sister, Karen, was abducted, raped, and murdered by spree killer Freddie Glenn.[10][11][12][13] In 1980, his twin half-brothers died in a scuba diving accident; and David Angell, close friend and producer of Frasier, died in the 9/11 attacks.[14][15]”.
That is an overwhelming amount of personal tragedy. He must see death around every corner. Perhaps at some point forgiveness becomes necessary just to get through another day.
