Britain's worst paedophile planned to "mould" one of his victims into his "perfect wife" - so he could get away with abusing more children, a court heard.
Richard Huckle, 30, is facing multiple life sentences after he carried out horrific sex crimes against up to 200 children in Malaysia over nine years.
He has admitted an unprecedented number of sex offences against poor Christian girls and boys in Kuala Lumpur between the ages of six months to 12 years.
Ahead of his sentencing, Huckle told a psychiatrist he wanted to put "all the madness behind me" and seek out a South Indian woman.
He also blamed his crimes on "external influences", according to the report.
But prosecutor Brian O'Neill QC, pointed out a disturbing post Huckle made in 2013 on the dark web site TLZ - The Love Zone.
It it, he detailed how he had abused four girls from the same family and earmarked one of them to be his future wife.
Describing how he had "fallen in love" with South Asia, he wrote: "I have gotten particularly close with one family whom I have known about six years.
"I have sexual contact with four of the girls in that family and though the family obviously does not approve it they try to work around it as they know I can be a potentially valuable asset to them in future."
On marrying one of the girls when she turns 18, he wrote: "I feel my situation could strongly benefit me in that my partner is still quite young and I have known her since she was seven and I can influence her young mind to mould her into the perfect wife.
"My ambition once married would be for our family to be like foster carers for children, temporary or long term."
He wanted to have children of his own but added he was "not a big fan of incest".
He went on: "With having such a long standing relationship with my wife and being over 10 years older than her I would hope I would be able to pacify and influence her into not reporting me as I would make it clear to her that she would lose her 'middle class lifestyle' if I got busted."
He added: "Marriage certainly is not suitable for a paedo to a western woman (there are women who would be safe but they would be extremely unattractive) but you can get away with it a lot more if you live in and marry a south Asian girl."
Earlier, the court heard how Huckle's parents were so horrified at what their son had done they begged police to take him away.
The freelance photographer, from Ashford in Kent, began the abuse on a gap year to south east Asia at the age of 19, and masqueraded as a devout Christian and English teacher to gain the trust of his victims and their families. He went on to post a stream pictures and video of himself raping children which were shared worldwide on the dark web.
He even set up a crowd funding enterprise inviting other paedophiles to pay Bitcoins for access to more images.
Acting on information, Huckle was arrested by the National Crime Agency when he touched down at Gatwick airport en route to spend Christmas at home with his family in 2014.
Mr O'Neill said Huckle was bailed to return to his parents' home after refusing investigators' questions.
The next day, his mother asked him about the allegations and he admitted he had sex with children.
Mr O'Neill said: "His mother was extremely upset and angry. She and his father called the police and asked them to take their son away.
"Both have made witness statements in support of this prosecution."
Huckle has admitted 71 child sex offences, including multiple rapes, against 23 identified children aged between six months and 12 years old.
However, the NCA were not able to crack all the encrypted files on Huckle's computer which could contain indecent images of far more victims totalling up to 200.
He will be sentenced at the Old Bailey by Judge Peter Rook QC.
