The lord of that servant ... will cut him in sunder, and will appoint him his portion with the unbelievers. 12:46
Trivia: According to Jesus, what will happen to the haves and have nots?
Why would they do that? Well, the Governing Body doesn't believe in a soul, so they say the good thief died like everyone else. Only later, nearly 2000 years later, after Armageddon, would he be resurrected. So they couldn't let Jesus tell him that he'd be with him that very day in paradise. Instead, they have Jesus say that he is telling the truth today (Not yesterday or tomorrow, but today. Or maybe "today" here is emphasizing that he's telling the truth today, but he was lying yesterday or something) -- and that sometime in the far distant future they'd be together in paradise. 23:43
