Ummmm.... Why does one indivdual have to take the blame? Most of the blame sits squarely on the idots who were told time and again to get the hell out of there. Yet they stayed because they didn't want to leave their home, pet, favorite chia pet plate, whatever. Or they stuck around to loot. Doesn't matter most of the blame for the pain and death belong on those idiots for staying.
Don't tell me they couldn't leave either. There were plenty of folks they could have caught rides with, busses trains, etc...
