I said this already elsewhere:
When using the word anointed from JW world, they are referring to those chosen to rule with Jesus.
The time of the 8th king and taking the MOTB has not come yet, therefore no one has been forced to take it or refuse it.
No one from the WTS from its start in 1879 to the present that have died already could have been chosen to rule with Jesus according to what is said about those chosen to rule with him, at least where it refers to the MOTB.
[4 And I saw thrones, and those who sat on them were given authority to judge. Yes, I saw the souls of those executed for the witness they gave about Jesus and for speaking about God, and those who had not worshipped the wild beast or its image and had not received the mark on their forehead and on their hand. And they came to life and ruled as kings with the Christ for 1,000 years.]
Partaking means nothing in regard to being chosen to rule with Jesus. If one was not killed for their faith in God and in Jesus or living during the time of the 8th king and was then killed while faithfully refusing him, they are not of the anointed to be chosen to rule with Jesus.
[9 When he opened the fifth seal, I saw underneath the altar the souls of those slaughtered because of the word of God and because of the witness they had given. 10 They shouted with a loud voice, saying: “Until when, Sovereign Lord, holy and true, are you refraining from judging and avenging our blood on those who dwell on the earth?” 11 And a white robe was given to each of them, and they were told to rest a little while longer, until the number was filled of their fellow slaves and their brothers who were about to be killed as they had been.]
