In the movie Nero, Nero killed his good friend and teacher, his brother, mother, father, and indirectly, his sister, his first wife and his second wife, and all the Christians in Rome and Paul too.

Now I can see why John in Revelation referred to Nero as the Antichrist in Rev. 13.18 by speaking of him having the number of a man.

Neron Kaisar in Aramaic = 666.

The Antichrist will be Caeser Nero reanimated, and he will kill Christians again.
