Most of these 'changed' verses are not changed at all. John 1:1 requires and insertaion of "the". Robert Pryce commented on this very fact awhile ao.
The 'impale' is a word change to keep up with torture stake. (In reality torture stake is valid since a cross is a torture stake)
The aforementioned John 8:1-11 does not deserve an answer!
However the largest places in the 1984 NWT were in the Old Testmanet. The changing of Jeremiah 5:8 to include testicles. The dumbass changing of Job 6:6 from Mallows to 'slimey juice of a marshmellow'.
The insertation of {other} in brakets in the NT is somewhat questionable as in {in union} but since the theology of each book preaches a different Jesus it is hard to harmonize the NT
The insertation of Jehovah into the NT is a half-done job since serveal translations have YHWH in the NT many more times then the Watchtower. The fact is that replacing the word Lord with Jehovah ruins the text sicne it is obvious that the author of the Gospel of John and many Pauline letters are not preaching the same God as YHWH but a higher God.(YHWH is a demierage)
