Yes, I can emphasize with being angry after being misled. I visited KHs and put literature on JW cars before I was run off the property. Constantly, seeking out JW in forums to expose their errors.
However, as I looked at the big picture and the example of the apostle Paul and his zeal as a pharisee, he showed in his letter to the Galatians that the law was a gift as a PEDAGOGY (Galatians 3:23-29) leading to Christ. If it were not for my search for the meaning of life as I studied with a work mate, I would not have come to appreciate the value of the scriptures. The WTS has the same record of success as does the AA and other support groups for a changed life. I believe the more we are responsible with what we learn from Gods dealing with imperfect creatures, the more capacity we have for more truth. As Christ said nobody can come to him unless the Father draws him, and nobody can reveal the Father except Christ. I now believe, I learned what I needed from the Watchtower org. as I took the good and left the bad. 1 Thessalonians 5:21 and moved on to a quiet life in Christ's peace.
