I doubt it.
Many on JWD and many I've spoken to, JWs and non-JWs, have chosen Christianity, just in case.
They are betting that it may be right.
If it is, they go to heaven/paradise and avoid hell/eternal separation from God.
If it isn't, we're all in the same boat, so it doesn't matter anyway.
They've lost nothing.
I can't speak to the personal case of Pascal.
Thanks for the additional info on him, Narkissos.
