Because it's apparently especially relevant TODAY:

"The death of human empathy is one of the earliest and most telling signs of a culture about to fall into barbarism.”

--Hannah Arendt,
Jewish survivor of Nazi Germany,
German-American historian and political philosopher,
1906-1975

EDIT
In replies, @ricardoharvin points out that barbarism has always been present in the USA.

He's absolutely right, and I appreciate the gentle, plain, but firm reminder.
