Not only should the WT be blamed for the "false expectations'' and the ''waiting accounts'' but also the New Testament/Covenant Bible itself for it teaches the underlying false expectations (including urging people to wait expectantly) and the false teachings of the nearness of the great tribulation, Armageddon, coming of Christ, and a new order. See the following NT Bible verses: Matthew 24:42-44, Matthew 25:13, Revelation 1:1, 22:18, 20. The Bible is also to blame.
If it wasn't for what the 'Holy' Scriptures Bible (both the OT and NT) itself also says, I would never have accepted the false expectations proclaimed by the WT and I would never had accepted the WT's teaching of urging (through its literature and public meetings) me (and others) to wait for the proclaimed events to happen.
