Pervert.
Did he suck on their toes?
I wouldn't be too quick to judge the Pope kissing the feet of women prisoners as being perverted. Would we consider the woman who kissed Jesus' feet perverted? It boils down to the heart and intent of a person.
"And behold, a woman of the city, who was a sinner, when she learned that he was reclining at table in the Pharisee's house, brought an alabaster flask of ointment, and standing behind him at his feet, weeping, she began to wet his feet with her tears and wiped them with the hair of her head and kissed his feet and anointed them with the ointment." - Luke 7:37,38
Washing the feet of a person you don't know, let alone kissing their feet, takes humility and the love of Christ.
What I would say is that the Pope and clerics, evangelists etc. need to consider this word before they put on a show:
"“Be careful not to practice your righteousness in front of others to be seen by them. If you do, you will have no reward from your Father in heaven." - Matthew 6:1
