She is entirely deserving of her vengeance against Odin, who was an abusive and evil husband, who practically banished his wife to Midgard, trapping her helplessly here. Freya and Odin have an abusive former marriage, arranged to stop the war between the Aesir and Vanir.
When his irresponsible and impetuous behavior reignited an ancient war between Asgard and Jotunheim, Thor was denied the right to become king, stripped of his power and hammer Mjølnir, he was banished to Earth by Odin.
As this transpired, Thor was fighting the Destroyer on Earth, which would culminate in his death. Odin, in the Odinsleep, would shed a tear and use his magic to end Thor's banishment, giving him the power to return to Asgard to confront his brother.

Why did Odin stab himself?
Odin's self-sacrifice
But he wanted to know everything and gain wisdom and knowledge of things hidden from him. This was a desire that drove him to sacrifice himself. He sacrificed his eye in Mimir's well and he threw himself on his spear Gungnir in a kind of symbolic, ritual suicide.
As the default King of Asgard, Odin is easily the most powerful being in his realm. Throw in the Odin Force for good measure—the tremendous magical energy the All-Father draws his power from—and he can easily destroy a galaxy with a mere passing thought.
Odin revealed that he wanted to gain a permanent peace between Asgard and Jotunheim by having Loki rule the world of the Frost Giants. Loki was disgusted by his own parentage and claimed that Odin could have never loved him the same way he loved Thor and would have never given him the throne.
Odin placed several enchantments upon Mjolnir prior to Thor wielding the hammer: This is reflected in the inscription on the side of Mjolnir, which states: Whosoever holds this hammer, if he be worthy, shall possess the power of Thor. For almost the entirety of Marvel continuity, this has exclusively been Thor.
Originally there was no restriction placed on the hammer for who can use it but after Thor's reckless behavior, Odin Borson placed an enchantment on it. This spell read "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor." Only those deemed worthy to lift Mjolnir can.
Freyja was the daughter of Njörðr, and was Odin's concubine. Odin deeply loved Freyja, and she was "the fairest of woman of that day". Freyja had a beautiful bower, and when the door was shut no one could enter without Freyja's permission.
She didn't care that her husband angered the gods as mortal even after he became a god himself she still loved. Though she cheated on him and loved many different men she was heartbroken when she found out he left Valhalla/Asgard because of her actions.
Unable to cope with her husband's growing madness and his even more despicable actions, Freya attempted to break free from Odin who, in a burst of madness, cursed the Vanir goddess and deprived her from her warrior spirit.
Hela despises anyone who stands in her way and will gladly eliminate all who stand in her way to ruling the Nine Realms and beyond, specifically Heimdall, Thor, Loki and Valkyrie, as well as outsiders like Hulk, Korg, Miek, and the world-crushing demon Surtur.
It is also implied that he has an intense fear of Kratos as well, as he knows nothing about him except for the fact that he's extremely powerful and having fought and killed one of his sons, Baldur and his two grandsons, Magni and Modi in battle.
The God Tempest always resented being trapped inside the hammer, and refused to be tamed even by Odin himself, who had to put protective enchantments on Mjolnir after failing to control its power.
Odin : Thor Odinson... you have betrayed the express command of your king. Through your arrogance and stupidity, you've opened these peaceful realms and innocent lives to the horror and desolation of war!

So while Zeus' best feat is defeating a mountain-sized monster, Odin's best feat is defeating a monster as big as nine worlds. Odin outclasses Zeus in intelligence, versatility, strength, and weapons. Zeus simply can't compete. The winner is Odin, All-Father of the Æsir.
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.
Granted, Zeus is probably much smarter than Thor is but in a straight fight there's not much he can do. Even in terms of weapons Zeus is disadvantaged. Zeus has his master bolt and that's it.
Odin stands a good chance at defeating a moderately-fed Galactus. Odin has been stated to be equal to a moderately-fed Galactus. Though Galan did withstand a powerful headbutt from Odin. The Devourer had just consumed one planet before that.
Having wielded the star-forged weapon for countless centuries, Thor and Mjolnir have quite the singular bond, despite the various trials and tribulations they've been through. And that bond is ultimately what proves that the Mighty Thor has surpassed his father, Odin.
