This paper investigates the link between (radical) evil and the existence of God. Arguing with contemporary atheist thinkers, such as Richard Dawkins and Victor Stenger, I hold that one can take the existence of evil as a sign of the existence of God rather than its opposite. The work of Immanuel Kant, especially his thought on evil, is a fertile source to enliven this intuition. Kant implicitly seems to argue that because man is unable to overcome evil by himself, there is a need for God to bridge the gap. Si Deus est, unde malum? Si malum est, Deus est!
