For Kant it is unimaginable that someone would want his own destruction—this would be diabolical. … On a certain level every subject, as average as he might very well be, wants his destruction, whether he wants it or not. It is this level that Lacan calls the death drive, and it is here that he situates jouissance. In other words, the “angelization” of the good and the “diabolization” of the evil is the (conceptual) price to pay for making the Real an object of the will, that is, for making the coincidence of the will with the Law the condi­tion of an ethical act. - Alenka Zupancic
