What has always been interesting to me is that the yes, there is a replacement for Judas by scripture, but the WT makes its own claims as to who is already judged for their second death as if they looked upon the book of life already.
Adam and Eve - I hear this a lot from ones as if its the absolute truth from Jehovah
Judas - Even though he was not faithful, we know nothing of his lafter after betrayal and if he repented. Afterall, he did God's will
Saul?
Ananias?
