Why does God allow evil? First thing we need is to define evil. What is evil and what is not evil? God said: Isa. 45:7
"I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things."
Just how did God create evil?
By defining it. When the third of the angels rebelled, they hadn't observed the results of evil. They set their hearts to do the evil and then they became fixed in their evil character. Now, they can't help but to be evil. All it takes for Satan to carry out his worst is for God to remove His hedge. Something obviously visible in the spirit realm. That is the only permission he gets. He does not meet with God and lay plans for his work, He is dependable/fixed to do it.
God is in the process of removing evil from the universe. God is a God of love. If He allowed the evil being to continue anywhere forever, that would be most unkind to them. Would not a God of love let anyone, that couldn't quite cut with Him, be destroyed instead of tortured forever. Some people are going to turn evil despite any influence acted upon them.
All this speculation about the fate of all unbelievers is moot. Even professing Christians that do not have the Holy Spirit, have no chance to serve God. Only the participants of the first resurrection have any chance of ruling with Christ.
There are many morally good people in the world, but unless our Father draws them into His fold: they will never understand God's word and His plan. We don't have to worry about anyone being tormented in flames forever. Romans 6:23 says the wages of sin is death. Everybody sins and everybody pays. This is physical death. The dead are asleep. Paul may have said: to be absent from the body is to be present with the Lord. OK, to close your eyes at night: presto - it is morning. It is the same principal.
God's promise to resurrect "the rest of the dead" in Rev. 20 will be the first and only chance these that were not called in the first life will have. That is when they will have their chance to overcome Satan and his fallen army. This will be Satan's last act. When God is finished with purging the universe of evil: all the demons and evil people will be completely destroyed.
Eze. 28:14:
"Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire." This establishes identity. Eze. 28:18, 19:
"Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee. All they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never shalt thou be any more."
This tells of the fate of Satan. Which is also the fate of those that reject the Holy Spirit anointing by the end of the judgement period.
