Russian president Vladimir Putin wanted world leaders to have regulations in store for superhuman soldiers in the future in case they turn in to mass killers who feel no pain or fear, The Express reported Monday.

The statement came after he warned attendees of the "World Festival of Youth and Students" Saturday. Genetically-modified superhuman soldiers are a possible danger, because scientists are close to breaking the genetic code.

"He can be a genius mathematician, a brilliant musician or a soldier, a man who can fight without fear, compassion, regret or pain," Putin said in his speech for the festival's closing ceremony, according to Express.

"What I have just described might be worse than a nuclear bomb," Putin proclaimed, in front of the 20,000 young women and men attending the festival, which was held in the Olympic Park in Sochi.

About 10,000 of the attendees for the festival, organized by World Federation of Democratic Youth (WFDY) along with the International Union of Students, were from other countries.

Putin shared his grim expectations of the future, underlining this was not a future he wanted to see happen. In fact, he wanted the world leaders to decide to develop ethical guidelines and strict regulations for that kind of "creations."

"When we do something, whatever we do, I want to reiterate it again - we must never forget about the ethical foundations of our work," Putin said in his speech.

He warned that this type of scientific experimenting could lead to serious consequences.

"A man has the opportunity to get into the genetic code created by either nature, or as religious people would say, by the God. All kinds of practical consequences may follow. One may imagine that a man can create a man not only theoretically, but also practically," Putin proceeded in his ominous speech, according to Express.

Last month, Putin revealed other futuristic fears when he asked chief of internet firm "Yandex", Arkady Volozh, when Artificial Intelligence (AI) robots will "eat us."

The unexpected question came while Volozh was discussing Artificial Intelligence and the potential it held for the future. "I hope never," Volozh replied, according to state-backed media outlet RT.
