After Loki got a glimpse of the tesseract, Thanos somehow learned about it and abducted Loki. Tortured, threatened, put on “drug” of some sort- may be the scepter or some other sort of energy, poisoned Loki's mind. I also think that if Loki wasn't under the influence, he would have stopped when Thor asked him to.
Instead, Thanos used the Mind Stone's immense power to influence Loki, without Loki being aware this manipulation was occurring. With Loki now under the control of the Mind Stone, Thanos could send him off with the scepter and not worry about being turned against.
Loki's magic is more about trickery and deception, utilizing illusions, shape-shifting, hypnosis, and telepathy. He can also levitate, teleport, create dimensional rifts, and manipulate objects with his mind.
One of his first technical connections to Earth came about when he employed Loki to attack the Earth and claim the Tesseract in The Avengers. To this end, he entrusted Loki with a powerful Scepter containing the Mind Stone, along with a massive army.
Here's How Thanos Originally Got The Mind Stone For Loki
Did Thanos manipulate Loki?
There you have it: Loki was as much a victim of Thanos and the scepter as anyone else, potentially, since the Mind Stone was driving him to be more evil and hateful than he actually was at heart.
At the end of the film, Loki was seen careening through space to his apparent death, only to resurface during the end credits scene. As we found out in 2012's The Avengers, Loki had survived his fall, but he was under the influence of Thanos. That wasn't the only time Loki faked his death.
Another theory, posted on Reddit, suggests that Thanos' real goal when he gave the Mind Stone to Loki was destabilizing Asgard so he could get to Nidavellir and have an Infinity Gauntlet made for him. Nidavellir is one of the Nine Realms, homeworld to the Dwarves, and the place where weapons like Mjolnir were created.
Even when he was power-hungry and arrogant, Loki was smart enough to know to fear Thanos. He was familiar with Thanos' past planet cleansing, and that is why Loki believed he was key in ruling Earth. He knew how powerful the Titan was, but more importantly, he knew how powerful the Infinity Stones were.
Loki's dangerous antics and menacing lifestyle puts others at risk. Like Loki, persons with BPD experience disturbing emotional outbursts such as bouts of uncontrollable anger or rage--often followed by shame and guilt.
This stemmed from his childhood and the belief that Odin didn't love him. While Odin's hiding of Loki's true parentage and Thor's demeaning behavior may have influenced Loki, ultimately he is to blame for his villainous actions due to his own issues with self-acceptance and misinterpretation of his upbringing.
In AVENGERS & X-MEN: AXIS (2014) #9, Loki found himself in the unfamiliar role as the hero when he confronted the inverted “evil” Thor on the moon. This version of Loki was so pure of heart that he was able to pick up Mjolnir and transform into a version of Thor.
In The Avengers, Loki tried to mind-control both Hawkeye and Iron Man, but while he succeeded with Hawkeye, his attempts failed on Iron Man due to his arc reactor. Iron Man's arc reactor protected him from Loki's scepter, as the scepter needed to touch organic matter to work, and the arc reactor was not skin.
According to the theory, when Loki was causing trouble throughout the first Avengers film, he was actually under the influence of the Scepter, which he wielded when it contained the Mind Stone: After Loki got a glimpse of the tesseract, Thanos somehow learned about it and abducted Loki.
In Loki's official character bio on the Marvel website, it states: "Gifted with a Scepter that acted as a mind-control device, Loki would be able to influence others. Unbeknownst to him, the Scepter was also influencing him, fueling his hatred over his brother Thor and the inhabitants of Earth".
Originally Answered: Why didn't Loki use the Tesseract against Thanos on the Asgardian ship? At the time, Thanos only had one Infinity Stone, and the Tesseract should have been able to hold its own against him, especially with the help of Thor and the other Asgardians. Simply because he doesn't know how.
Loki's always been good at planning things and sticking to the shadows. He had this plan to sacrifice himself to ensure Thanos' death, and his plan worked. It WORKED, which means Loki didn't die in vain, he died saving literally the entire universe.
Loki, despite his past actions, is given a chance to be a "good guy" and redeem himself, unlike other villains. Loki's popularity and sympathetic persona contribute to his extensive redemption, making him one of the MCU's beloved characters.
Answer and Explanation: According to Norse mythology, Thor dies in an epic battle with a monstrous serpent named Jörmungandr, also known as the Midgard (middle earth) Serpent. Both opponents meet their death in this battle, which is a part of the ultimate destruction of the current world, known as Ragnarök.
Loki is married to Sigyn and they have two sons, Narfi or Nari and Váli. By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir, and the world serpent Jörmungandr. In the form of a mare, Loki was impregnated by the stallion Svaðilfari and gave birth to the eight-legged horse Sleipnir.
Marvel Comics gave fans a peek into the true motivations behind Thanos' actions, confirming that Loki knows more about Thanos than the MCU does. In a recent peek into Thanos' true motives behind his villainous actions, Marvel Comics confirmed that Loki knows the Mad Titan better than his own MCU movies.
Loki has always delighted in cheating death, manipulating others into believing he was dead in order to hatch his next scheme. At the end of Thor, he apparently took his own life — but Loki survived death by plunging into one of the many portals he knew could be found in Yggdrasil.
Crucially, Loki's final words to Thor were: "I assure you, brother, the sun will shine on us again.” It's a poetic sentiment, but it may also be a direct link to Thor harnessing the power of a dying sun to make Stormbreaker. Either way, Loki's message sounded like a promise that they would see each other again.
