Question of purpose

A writer, a person to lay words, in rows and columns, personify life, reporting, tasting , crying, laughing but mostly sharing. A view of personal experience tried. Background seeing believing hand in the side, fingers in the holes, pictures burnt deep into memory, voices screaming, mental images held hard, body parts cast, smell of death touched and felt to the soul, man no excuse, mental giant left to fight for crumbs, picture cast to page, read loved and hated, truth holds no place as want and need, hungry is till hungry and death is still death and torture is man approach, to gain grains of sand.  A writer, I wonder, why?
