As for the devil and the false prophet being tormented forever in Revelation 20:10 : First, the English word "ever" (in forever) is the Greek word "aion", which means age. This is the same Greek word used for the English word "world" in Matthew 24:3 talking about the end of the world (i.e. age). Scripture says the beast in the false prophet will be in the Lake of Fire for 1,000 years. However, the beast and the false prophet are demons and not humans. They had inflicted pain and suffering on humanity for more than 1,000 years. Second, when it says forever in Revelation 20:10 it is a colorful expression of strong emotion for the totality of the devil's allotted time of punishment. It is a strong expression of emotion of totality. Sort of like how a man might say to his wife in love, "I am your husband forever." However, he knows he won't be her husband forever because he knows death will separate them as husband and wife in the future. But what evidence is there that Satan will perish in the Lake of Fire with everyone else?
Well, you may or may not know this, but Isaiah 14:12-20 and Ezekiel 28:11-19 are well known verses amongst Christians that talk about the devil. They are passages that describe both the devil and the evil rulers who were living during that time. Anyways, Ezekiel 28:18 says that the fire will devour the devil and he will be brought to ashes. Isaiah 14:19 says the devil's carcase will be trodden under foot. Meaning he will be nothing but a charred up corpse or a destroyed spiritual body.
Also, Scripture says the last enemy to be destroyed is death. This makes the assumption that there are other enemies before death that have been destroyed (Whether death is physical entity and or a power).
In any event, I hope that what I said here has comforted you. But please do not take my word for it. Search the Scriptures for yourself and pray over them and double check it for yourself. Let the Lord guide you into all truth by asking Him (Jeremiah 33:3).
