In Luke 13, the Galilaeans and those 18 under the Tower of Siloam were used as examples of tragic events.
Human responses to tragic death events are often indulged in compassion towards the victims. Hence, Anthropocentric.
But Jesus however, corrected this by bringing up repentence of the living as priority. Theocentric.
Anthropocentric principles could only lead to vanity and death; Theocentric attitude sees light and life.
