Determination. Thor is known for having a bad temper, yet his determination is also among his biggest flaws. Thor's perseverance is a weakness since it puts his life in danger because he continues putting himself in dangerous situations.
Thor's main fear is losing his worthiness because it would mean he isn't fit to protect Earth or lift Mjolnir.
He violated an ancient treaty and almost started a war
Remember, Thor didn't travel to Earth to fight for justice, to stop evil, or to protect the innocent. He was banished to Midgard by his father, Odin, because he was an unrepentant jerk who caused all kinds of problems and needed to learn some humility.
Thor blames himself for all the people dying because he was the person with the best chance of killing Thanos. Where did the asgardians come from in endgame? We know Thanos blew up their ship at the beginning of infinity war and the sole survivor was Thor.
He was rendered unworthy, because in his heart he believed what Fury said was true. In effect, Thor knew “how it feels to be mortal” and in his mind mortals are unworthy of Mjolnir and the powers of Thor. It's important to note here that Thor's unworthiness was of his own design.
Psychiatric illness, as it relates to Thor, is a multifaceted subject: Thor's depression may be combined with sensory loss, altered body image, and Post-Traumatic Stress Disorder (PTSD), which can serve as an impetus for further analysis of Thor.
' And the weight gain was just part and parcel of that state of mind.” The screenwriters said they deliberately ended “Avengers: Endgame” with Thor still in his heavier state to prove that his weight was inconsequential to his arc in the film. “He's emotionally resolved.
Worthy Warrior and Weaponry
Thor, son of Gods, has enhanced longevity, augmented by the Golden Apples of Idunn. He also possesses superhuman strength, speed, agility, durability and immunity to most diseases.
Thor is one of the most prominent Marvel heroes, who's fought alongside the Avengers to protect Earth from the biggest threats in the universe. But, in one Thor tale, the government didn't see eye-to-eye with the God of Thunder, which resulted in a war that led to an evil Thor rising and ruling the planet.
Among Thor's more clear-cut enemies stand Frost Giant King Laufey, Surtur the Fire Giant, the dark elf Malekith, and Thor's own half-sister Hela, the so-called goddess of death, all of whom have ill intent towards Asgard.
Of course we know that Thor Odinson was eventually deemed worthy enough to wield the hammer. That is, until the events of Original Sin where Nick Fury whispered something into his ear that caused the hammer to deem him unworthy and reject him. That's how Jane Foster came to be the hammer's current owner.
Thor has become unworthy of using the Mjolnir in both the Marvel Cinematic Universe and Marvel Comics, but for very different reasons. The god of Thunder's debut in the MCU centered around his exile to Earth as a mortal and his unworthiness to wield the Mjolnir.
The short answer is yes, Thor is still worthy of lifting Mjolnir after Thor: Love and Thunder. His worthiness comes down to the reason why Mjolnir chose Jane. In the comic books, Mjolnir does choose Jane to be Thor after Thor becomes unworthy and is unable to lift it.
Thor has been defined by his weapon and whether or not he can lift it. While losing Mjolnir undoubtedly makes Thor a weaker fighter, but a much stronger character; now, the question of worthiness is up to him, and he cannot rely on a weapon to tell him if he's doing the right thing.
Thor is Immortal, Not Invincible
Thor is more or less immortal, granted the gift of everlasting life, thanks to his Asgardian genes and his special diet of the Apples of Idunn. In Avengers: Infinity War, Thor revealed that he was over 1500 years old.
Thor can survive in the heart of the Sun with no discomfort, has flown through the heart of stars, and survived point blank range energy explosions capable of destroying entire planets.
Superhuman Stamina: His stamina is almost limitless. Thor survives the Time Stone of time. While still aging physically, he retains his youthful appearance far longer than humans, barely changed after Thanos used the Time Stone to age by several centuries, and will only grow stronger the older he gets.
Love and Thunder highlights this problem. In the opening voice-over, Korg explains that Thor is vulnerable and conflicted because he's lost so many people close to him.
Due to his strained relationship with Odin, Thor frequently falls back into his old ways and resumes drinking, much to the dismay of Sif and Thrud. This only gets worse after the deaths of Magni and Modi, as Thor blames not only Kratos and Atreus but himself as well (though he would never like to admit it).
Both Jane and Thor started to withdraw from each other, they both were experiencing the loss of their relationship. It was a mutual breakup because they both left each other, yet the love still remained. Often heartbreak can lead someone to harden their hearts to love.
Intelligence: Superhuman Level 35 (can process information requiring up to a 29,000 IQ) to Superhuman Level 44 (up to 74,000 IQ with God-Force), Superhuman Level 48 (up to 94,000 IQ) as Rune King Thor.
Loki's complex emotional patterns are consistent with someone who has Borderline Personality Disorder (BPD), a mental health condition characterized by difficulties with regulating emotion.
In a moment of wistful affection for his girlfriend, Thor asked his trusty hammer to always protect Jane, and in doing so unwittingly enchanted Mjolnir to do just that. Just like Thor's father Odin once enchanted the hammer to only be lifted by someone who is worthy, Thor cast a spell that let Jane use its powers.
