If you believe there exists a soul for which judgement awaits, the transporter paradox is HORRIFYING.
Imagine seeing the pearly gates and finding a line of alternate yous who also used a transporter. If you're judged only on your actions, each of yourselves will be judged differently.
There are Gul Dukats and Khan Noonien Singhs in trek heaven who just slept between transporter journeys.
Still capable of evil, never repented, but still getting a ticket upstairs.
