This is a previous post that is my gift to the world.
"Loki doesn't want Thor dead. Loki wants Thor to kneel. Loki wants the Throne of Asgaurd. And maybe that might have been the trade for earth but I have a different idea. Thanos was controlling him during the battle in the Avengers so he sought out the Hulk because knocking him senseless was the only thing that could eventually break the control. Why else did Loki look in such poor health? He was pale and waxy and could hardly function. We all saw him collapse into the back of a truck panting right? That's what happened to Loki. Thanos found him, tortured him into submission, and turned him into a pawn. This is where the "freedom is a great lie" comes from because it was beaten out of him. That's also why he is a little crazy because he was again, tortured. Also we all know his eyes are green, yet his eyes where blue. Loki purposely failed. Where was he banished from sort of? Asgaurd. And by failing where is he being returned to? Asgaurd. Loki played Thor like a fiddle even in his state.
Also by putting Loki in a cage he would be safe and have time to formulate a plan of escape. The dark elves coming just brought about his escape faster than he expected. So when Kurse came he knew the only way for him to get out was if Asgaurd was in a state of chaos so he told Kurse where the sheild control was AGAIN THE SHIELD not where his mother was...we saw Kurse turn the wall off, then he met up with Malekith who went after Jane. So it wasn't Loki's fault his mom died. So for the people who think it was his fault it wasnt. Once in a state of chaos Loki probably had a plan but when Thor came in need of help he got out even faster. Then he knew he had to eliminate himself from the equation. The only way Loki would talk free was if he was presumed dead. So Loki played along until he wasn't needed anymore. He did actually get stabbed I think since illusions disperse when you touch them but I think he had healing stone like Thor had in the first movie he used in a deleted sene. That or it was just a good illusion. Regardless he faked his death/got really lucky.
What happened in Thor the DW still is very fuzzy because we've yet to see Ragnarok where we will probably get some answers because Thor will be like "Loki how in the nine realms are you alive! I watched you die!". Anyways when Thor is leaving the palace with Loki before hand he takes the form of a guard. The same guard who brings Odin the news of Loki's "death". Loki has done something to Odin....and we know that Thor and Loki aren't fighting the whole movie because of the clips we saw of them filming in Australia (I think that's where). All we know about what happens next is Loki sort of makes a deal with the devil (Hela) and it probably goes south for him and him and Thor have to go get Odin to defeat her and somehow the Hulk and Thor face off to save Asgaurd...I'm so confused about Ragnarok.
So I basically explained Loki's deal, or at least what I think happened. Also the whole Loki being controlled by Thanos might leave the opportunity for Loki to fight with the Avengers, Thor, Sif and the Warriors 3, The Guardians of the Galaxy, Doctor Strange ect, against Thanos (aka the redemption all of us want for Loki) or with Thanos because of his prior brainwashing/control"
Also as for his behavior in Thor. He let the frost giants in to impress his father when he killed them and saved his life when Laufy was about to kill Odin. Remember when he said that in Odin sleep he hears and sees everything? He knew so he wanted to look good and finally be praised. All Loki did in Thor was to try to impress his father it wasn't malicious until he realized the warriors 3,Sif,and Himendall betrayed him and told Thor everything. He sent that robot thing down to kill Sif and the warriors 3. Not his brother.
Loki is a deeply hurt person. He didn't handle it well but you can empathize greatly with him and even see yourself in him if you've ever had a dominating/older sibling. I want Loki to find Sigyn. Like marvel please.... LOYALTY AND LIES they're polar opposites but Sigyn would be with him to the end. She would be intellegent,brave,kind,beutiful inside and out, a ball of sugar, a Frigga like figure, and most importantly unfailing loyal. She should tell him the story about beauty and the beast and would relentlessly show him how wonderful he is and can be. She wrangles him in with her calming presence. He'll hurt her and feel awful because she reminds him of her mother and cant stand the guilt and hate himself for loving her....Thor would love Sigyn and would be like "thank the 9 realms you came along"
SOMEONE STOP ME *lunges on self* wrangle your Loki x Sigyn mythology ship.....
