Egad! What kind of theology is this! Whatever your views of Revelation may be, there can be no doubt that hell was created and is controlled by God.
BTW-Satan is not the ruler of hell. Since God is omnipresent (everywhere), God has to be in hell as well. Everyone in heaven or hell will bow down to His glory.
Sin is the cause of Hell existing and Hell is eternal separation from God. Thus if satan had not fallen Hell would not exist.(of course thats as they say "water under the bridge")
From the Catechism.

1037 God predestines no one to go to hell;618 for this, a willful turning away from God (a mortal sin) is necessary, and persistence in it until the end. In the Eucharistic liturgy and in the daily prayers of her faithful, the Church implores the mercy of God, who does not want “any to perish, but all to come to repentance”:619
635 Christ went down into the depths of death so that “the dead will hear the voice of the Son of God, and those who hear will live.”484 Jesus, “the Author of life”, by dying destroyed “him who has the power of death, that is, the devil, and [delivered] all those who through fear of death were subject to lifelong bondage.”485 Henceforth the risen Christ holds “the keys of Death and Hades”, so that “at the name of Jesus every knee should bow, in heaven and on earth and under the earth.”486
Here is a few things from the Catechism
413 “GOD DID NOT MAKE DEATH, and he does not delight in the death of the living. . . It was through the devil’s envy that death entered the world” (Wis 1:13; 2:24).
395 The power of Satan is, nonetheless, not infinite. He is only a creature, powerful from the fact that he is pure spirit, but still a creature. He cannot prevent the building up of God’s reign. Although Satan may act in the world out of hatred for God and his kingdom in Christ Jesus, and although his action may cause grave injuries - of a spiritual nature and, indirectly, even of a physical nature- to each man and to society, the action is permitted by divine providence which with strength and gentleness guides human and cosmic history. It is a great mystery that providence should permit diabolical activity, but “we know that in everything God works for good with those who love him.”
