Item: Our position is not the same as the serpent telling Eve that she would not surely die. The Bible is clear that only those alive when the Savior appears as King will "not surely die."
Item: Does God really torture? After an extensive word study, I have concluded that all the fire in the Bible which is not natural fire is Godfire. The Lake of Fire is Godfire. Those in it get a full and personal dose of Godfire, but I doubt it will be pleasant, and who of us will not need some refining? I'm certain I do. The Bible says, "Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby." - Hebrews 12:11, KJV
Of course it is God fire!! It is totally destroys what is not protected by the blood of Christ.
Deu_4:24 For the LORD thy God is a consuming fire, even a jealous God.
Deu_9:3 Understand therefore this day, that the LORD thy God is he which goeth over before thee; as a consuming fire he shall destroy them, and he shall bring them down before thy face: so shalt thou drive them out, and destroy them quickly, as the LORD hath said unto thee.
2Ki_1:10 And Elijah answered and said to the captain of fifty, If I be a man of God, then let fire come down from heaven, and consume thee and thy fifty. And there came down fire from heaven, and consumed him and his fifty.
2Ki_1:12 And Elijah answered and said unto them, If I be a man of God, let fire come down from heaven, and consume thee and thy fifty. And the fire of God came down from heaven, and consumed him and his fifty.
Rev_20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
Job_1:16 While he was yet speaking, there came also another, and said, The fire of God is fallen from heaven, and hath burned up the sheep, and the servants, and consumed them; and I only am escaped alone to tell thee.
Eze_20:47 And say to the forest of the south, Hear the word of the LORD; Thus saith the Lord GOD; Behold, I will kindle a fire in thee, and it shall devour every green tree in thee, and every dry tree: the flaming flame shall not be quenched, and all faces from the south to the north shall be burned therein.
Eze_28:16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
What you are describing is the chastening of the Lord's righteous. In this life we are going to have trials and tribulations, these are a refining fire to us and bring us closer to God. To the wicked these things only make them hate God. And the end will be what they want it to be---the devouring, consuming fire of the Lord that does not refine, but destroys. There are only 2 choices that must be made before He comes.
Mat_12:30 He that is not with me is against me; and he that gathereth not with me scattereth abroad.
God is not going to force anyone to submit to Him. It is eternal life, or eternal death. Not eternal torture---but eternal death.
