The Greeks were great ones for summing up human existence in their myths about Hades and the punishments metered out to individuals. Tantalus who bent down to drink to find the water immediately receded and lifted his hand to grab at the grapes above him to find they pulled away. Sisyphus who had to roll a heavy stone up a hill and see it roll down to the bottom again. Ixion bound to his burning wheel and Tityos who, Prometheus like, had his liver eaten by vultures every day.
Of course these stories are the bad things that happen to bad people, people who overstep the accepted bounds of civilised behaviour; they kill guests, lust after chaste women, kill their family and so forth. It is all extreme and designed to show children what will happen to them if they become evil.
The problem with myths like this is that they do not decry all lust or all killing, just certain lusts and certain killing. And these special examples can change with the mores of the nation. There was no time when lust and killing hasn’t follow soldiery around the world and more often than not we give medals for it.
It isn’t by scaring children that we will gain a measure of their obedience; it is by teaching them to understand themselves and the immense bad and the immense good of which they are all capable. Showing them love is the best way to teach them to love.
