If you like, we could compare a single Thiel adulthood to individual randomly chosen lives of popes. The average pope has a lot more blood on their hands. Both are bad, but one has caused more harm to humanity no matter which way you slice it. To argue that a single heretic is worse than the whole catholic church rings pretty silly to me. The best would be if they were to both destroy each other, but let's be real and acknowledge that Peter Thiel is going to die and become irrelevant long before the catholic church, which may very well continue on for another two thousand years for all we know.
What is the average pope? Fabian? Felix IV? Linus? Eusebius? Pius IV?
