"For the humiliation a girl would have if they put her face on a porn star's body, and then sent the video around to everybody in school … Not only [damaging their reputation] but simply damaging them."
The new technology, he said, follows a trend set by "revenge pornography" – a social media practice in which angry exes distribute nude photos or videos of former romantic partners.
"There has been a spike in suicides [because of] revenge pornography among young people, Kilcawley said.
A 2015 BBC analysis found that of 1,160 reported revenge pornography cases in England, 30 percent of the victims were under the age of 19.
With the ability to feed an algorithm photos found online, Father Kilcawley expressed concern that face-swapping porn videos will also be used for revenge pornography, and, because of the advancements in technology, they will be even more damaging to young women than real photos or videos.
"It will be equally dangerous to someone's soul who would be consuming it, but I think socially it may inflict a lot more damage than we are thinking about right now," he said.
Fradd told CNA that Catholics should respond to pornography with the wisdom of the Church.
"I think the Church has the answer to what is the human person and how we can be happy, just like the nutritionist has the answer to what should I be eating if I want a healthy body," he said.
Pointing to John Paul II's theology of the body, Fradd said the only proper response to the human person is love, and pornography always contradicts love.
"Wojtyla says the human person is a good to which the only proper and adequate attitude is love, but when we consume pornography we are always engaging in something contrary to love, namely use."
