So really, what benefit do they get by converting?
They take on a self identity of righteousness before god, in his approval ready to catch that ticket to eternal paradise.
The wicked world to them is soon to come down as promised so subconsciously they are internally happy, the most happiest people on earth.
They accept the fulfillment of prophecy happening all around them in their minds.
In the mean time they get some redemption from their sins (thank you Jesus) and some direction which they have been told they need to stay righteous. (thank you Watchtower Corporation )
They cant wait for Armageddon to occur, the really good stuff will come after that.
Bring it on Jah, your will be done as it is in heaven.
