American English is the far more conservative dialect—hence why it uses big Latin-origin words where British uses short Germanic ones. American retains a Renaissance preference for Classical derivations, while British English underwent a deliberate program of Germanization during the 19th century (they even coined words like "steadholder" to replace "lieutenant").

They have an afterlife in Star Wars, and "hell" is a serviceable translation of almost every culture's conception of the "land of the dead"—unpleasant afterlives are the rule, not the exception, in worldviews as disparate as Aztec, Shinto, and pre-Maccabean Jewish.

"B.C." is English; the Latin equivalent is A.C. (Ante Christum) or A.C.N. (Ante Christum Natum)...and is modern Latin, anyway, older Christian sources dated from the conception, not birth, of Christ (which isn't abbreviated B.C. anyway).
