Hmm. Wonder what religion fosters a belief in ‘paradice’ vs. heaven? And says that there will be ‘slaves’ to make their time in paradise easier? Sure sounds like... nah, couldn’t be the religion of peace, could it?
There’s also a town in California called Paradise, which was previously spelled Paradice.
The Zodiac killer also had a M.O. of misspelling words, so that could be another reason.
