The JWS use the death of people as a exploitation vehicle to promote their resurrection doctrine and their religion as a whole.
Yes they talk a little about the individual and their service to Jehovah, talks, participation in the congregation so forth but I think they go overboard.
Most JWS funerals are attended by a portion of non JWS and the JWS intentionally use these events to lure people to the organization, kind of propaganda in action.
JWS funerals are designed and outlined by the WTS with a specific purpose in mind .
I think it would be better to talk a bit more of about the person by people who knew them and perhaps a little bit at the end about the resurrection doctrine.
