Except the boy didn't have a name until the Wonderswan remake which was years after FFIV. The boy was unnamed originally and when Square remade the game for the ill-fated Wonderswan, they named the boy after Kain from FFIV.

Kain is named after the Biblical character, made most obvious by the fact he tends to get a weapon in later installments like FFIV Advance and FFIV:TAY called Abel's Lance. If you look at any of the Japanese source material, his name is spelled Cain. It was changed to Kain cause Nintendo USA had strict policies about religious issues in games. How BoFII got under the radar will always be a mystery though...

Also Golbezza (Golbez's actual Japanese spelling) and his Four Fiends are all named after Biblical demons from the Apocrypha Books of the Old Testament and other Jewish writings.
