H, I can't really see what you are upset about. The notion that human death (especially corpses that are starting to rot) have a sweet (sometimes sickly sweet) smell is often expressed by reporters of mass death scenes and has been as long as I can remember. For example, her is William Hicks reporting for Life magazine on 3 September 1945: "We saw Hiroshima today - or what little is left of it ... the sickly sweet smell of death is everywhere".
