If anyone wants to see some satanic shit under the vatican. Watch this skip to 1:45 they have an upside down cross. The preists even says this is the symbol of St Peter's Basilica. https://youtu.be/fi67NKGkovM

So Saint Peter requested to be crucified upside down. I highly doubt anyone would request to be crucified upside down. Satanic shit stretching back to Nero. Christians have been slaughtered for years. Take a look at the catacombs under Rome. This is totally fucked up.
