 This is however not a final argument, given the nature of Dostoyevsky's work as polyphonic.In the novel, the character Ivan Karamazov presents an account of incredible cruelty to innocent people and children to his theist brother, Alyosha.Following this, Ivan asks his brother if he would, hypothetically, choose to be the architect of the eternal happiness of mankind, which would come into existence, if, and only if he would torture an innocent child, a necessary evil, after which this eternal happiness would 
come into existence.
