What is Satan’s purpose?

Does Satan weed out the crop? Does he force as many people as he can to worship him and receive the spiritual mark of the beast (666) on their soul located at the person’s forehead or hand? Does he do this through the NWO / Nazis Within the Orders / Mafia's / Illuminated Masons secret ceremony of transcendental meditation performed with witchcraft / demonic forces? Is it through the distribution of occult games and or practices into society that this underworld Satanic Secret society has learned how to place people into spiritual / manifesting witchcraft to the point of enslaving society in this manner? After Satan forces as many victims as he can to receive this spiritual mark does he work through humanity by the manifestation of the spirit of sin and his demonic powers, through his minions, to create / manifest war in a global scale? Does he manipulate humanity to come against Jerusalem and others countries with the intent to try and end the world reaping his crop of the dammed / New World Order (AKA the destroyer)? Would that be spite or what? Does Jesus return to earth in order to stop the world from ending setting up his 1000 year millennium reign? Is this because of the chosen elect still to be born, those god fore knew since the begging? Does Christ return to reward the prophets and those who fear his name both great and small and to destroy those who destroy the earth?
