What is the saddest thing you've ever seen?

An Indian man carrying his wife’s dead body all by himself for 10+ kms.
His wife died due to TB in a hospital and the hospital refused to transport her body back home.

This man had to carry his wife’s dead body and at the same time console his sobbing daughter.

This is by far the saddest thing i have ever seen..
