Russell and others made the same mistake as many other Christian groups down through history including many of the Reformers. Convinced that they were living in the "end times" they interpreted prophecy by the events of their day. Many of them seemed to "fit the picture." And they thought that they had "the truth."
I remember thinking in the 1950s that conditions could not get much worse. The Watchtower's explanations seemed correct. Since most other religious organizations were not interested in the Bible and prophecy, I thought this organization was unique and God directed. Of course, I was young and naive. I knew little about the Bible and less about the history of the history of the organization.
But we should not berate ourselves as having "wasted our time." There are always positive results that come out of the worse experiences. If nothing else, we learn what to avoid and how to spend the remaining time left. Sadly, many people leaving the organization abandon themselves to hedonism and unbelief. And that is worst than having stayed in the organization.
