#AlanAlda explored themes of empathy throughout the run of “M*A*S*H,” but especially in the series’ final episode, in which Alda included a nod to stories he’d heard from World War II and the Korean War. Alda told Dr. Jon LaPook about his continued focus on empathy as a tool, including in a conversation he had with “The Pitt” star Noah Wyle. Watch more of their conversation Sunday.
