When Ragnarok comes around, Loki will be redeemed by helping Thor stop it, and he’ll say his famous line “FOR MYSELF!”. That’s it. That’s the only way he’s gonna be redeemed, and it’ll only be because all of existence is in danger and no one wants to deal with that.
There won’t be a “happily ever after” where he moves into Stark Tower with the Avengers and becomes this loving person who cares about mortals and everyone. In his eyes, he’s been betrayed and hurt, and everyone needs to see why they’re wrong for doing that to him. It’s not gonna go away because Thor gives him a hug.
