Kind of live and let live. They know they lose and are condemned to hell for all eternity. Now satan hates all of humanity regardless of their religion or lack of it. We are all created in the likeness and image of God, who satan detests. We're talking about a knock down, no holds barred fight to the death.
Christians have the same mission.
Satan murdered Jesus and thought it was over. If we have any other mentality, we had better wake up. Look at the current state of affairs in our schools. This is not about guns or security. We took God and prayer out of our schools and gave the devil free reign over our kids because we were too apathetic and weak to stand up for the Truth.
