Made some bad predictions? Well, those other religions that make bad predictions do not force their members to believe them without questioning them. Nor do they expect people to sell out because of the end being within a couple of years, only to blame the members when the end doesn't come and they end up in severe hardship.
As for the fruitages of God's spirit? You mean repression, stagnation, and non-fulfillment? Stifled desires (of the totally natural type at that)? Confused, biased, or just plain wrong views on morality? Justifying God killing people that simply will not cater to His senseless and stifling rules? To me, that is the true fruitage of God's spirit.
On top of the fruitages unique to the witlesses--protecting pedophiles and silencing the victims? Systematic abuse of children in other ways? Keeping children up past their bedtimes on school nights? No independent research? No education beyond the high school level? Poverty and stagnation? Always being tired and in a rush to get to a boasting session or field circus? To me, it is not worth displaying those fruitages. Instead, I would rather have the fruitage of the flesh--fulfillment of those desires with which I was born.
