"Weep not for me, but weep for yourselves" Jesus said, in Luke 23:28.
In Luke 13:1-9, the tower of Siloam incident and persecution of the Galilaeans were brought up to contrast between human judgment, sympathy and sobriety in repentance.
The people of older times are more inclined to link disasterous fate to the possibility of offending a greater power; Today, these are more inclined to link tragedies to something or someone, even God, other than the victims to blame and using that as the motivation to do charity.
In between these periods, our Lord has taught it differently. Instead of making sympathy and caring as priority as today's priests do or justifying the living upon the destruction of the dead, Christ teaches that we are to examine ourselves in repentance when news of disasters reaches our ears. For there is only one most crucial question on top of other vain inquisitions: Why am I still alive?
One who fears God and then does good is not the same as one who does charity and fears not God.
