"Having failed to impose his will on God, Cain inflicts it on Abel in the most ultimate form, by murdering him. Cain does not fear freedom. On the contrary, he relishes it. What he fears is someone else's freedom: the freedom of God to say 'No'. He takes his revenge by denying Abel the freedom to be. That is what is wrong with the will to power. I purchase my freedom at the cost of yours."
- Jonathan Sacks
