St Peter was the only real Pope because he was a True disciple of Jesus Christ, Nero murdered him and replaced him with his own pagan/luciferian false prophets aka anti-popes.
Why was St Peter crucified by Nero?
His execution was ordered by the Roman Emperor Nero, who blamed the city's Christians for a terrible fire that had ravaged Rome. Peter requested to be crucified upside down, as he felt unworthy to die in the same manner as Christ.
