I have delivered a couple of funeral talks, and Escargot is right: the outline does mention that the deceased is not to be eulogized, but rather, most of the talk should be used to share the 'hope' that is presented in the Bible. Needless to say, such unfeeling funerals have disturbed at least some of the people who have been present at them over the years.
However, I will say one thing positive about Witness officiating at funerals (and weddings as well)...they do not charge money for them. When an in-law of mine did suddenly and tragically, the church official stipulated that $75 was to be paid for performing the service. In my opinion, that charge should have been waived. It's tough enough having to foot the bill for a funeral, but then the grieving are asked to pay up for a church service. That sucks.
