Rev 14:10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
Rev 14:11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
The beast is the false Christ, are you saying, when forced to choose between the true Christ and the false one, and you choose to take the false Christ's mark upon you, choosing to worship the false Christ instead of the true Christ, and yet you will be saved?
No amount of theological gerrymandering can change the obvious intent of this passage.
The key may be in the tense of the verb “worship” in 14:9.
There is action that ceases after a while, and then there is action that continues forever and ever. Pretty sure the latter is being used here in the Greek.
This is why a different fate could apply to different tenses in the situations.
English can hide details that the Greek reveals.
