Saint Thomas Aquinas (always a good source for a Catholic theologian to trot out) raised the question: if God is everywhere, is God in hell? His answer is, yes. God is in hell. Then, with his usual rigor, Thomas asks the next question: what is God doing in hell? And he replies that God is in hell loving the damned. The damned may refuse to be loved and they may refuse to love in response, but the damned cannot cause God not to love them; they cannot make God be not God. They exist because they are loved and loved absolutely.
