Who is to say that Thor did anything? He found some kid who was Loki reborn in a manner similar to all the other Asgardians. I wonder if it would truly change anything though since he'd still be Loki no matter what. Also note that the clones Doom had all looked like Frost Giants, but then I've never gotten whether Loki always had some sort of glamour up or what.
The universe hates Loki no matter what incarnation he is. I can only hope for some nice moment between him and Thor. Maybe they can go for milkshakes.
