Rudolf Hoess related before his execution how he often felt weak-kneed at having to push hundreds of screaming, pleading children into the gas chambers:"I did, however, always feel ashamed of this weakness of mine after I talked to Adolf Eichmann. He explained to me that it was especially the children who have to be killed first, because where was the logic in killing a generation of older people and leaving alive a generation of young people who can be possible avengers of their parents and can constitute a new biological cell for the reemerging of this people."
