You gave a reply back but you did not answer the questions.
Anyway, I know and you know that your answer would be that you would not want those 3 men on the island if those are the things they would be doing. If you were one of the 1,000 adults then you and the other 96 would agree that they must go and you would agree that you are justified in removing/killing them. It would not be an unloving thing to do but to the contrary it would be a loving thing for the sake of the 500 children and the 97 adults.
You can distort the picture of God and Armageddon to fit inline with what you think it is but the truth is ONLY evil ones are killed.
