The idea of progress did not exist in the Greek underworld – at the moment of death, the psyche was frozen, in experience and appearance. The souls in the underworld did not age or really change in any sense. They did not lead any sort of active life in the underworld – they were exactly the same as they were in life. Therefore, those who had died in battle were eternally blood-spattered in the underworld and those who had died peacefully were able to remain that way.
