Granted it's not going to work but whatever war that's coming to Asgard in Thor 2 could be Loki's doing.
Odin and Thor will find out about Loki consorting with Thanos soon enough. Thor already asked him to confess who his "supplier" was; and now, facing punishment from Odin himself, he'll definitely have to 'fess up. Willingly or unwillingly.
Plus, I can't see (a) Thanos agreeing to give Loki a second chance and a new contract, ever; and (b) Loki keep giving away the most powerful items in the universe to Thanos (Cube and Gauntlet) rather than keeping and using them himself. The trust level between Thanos and Loki --- on *either* side --- has dropped to less than zero after the events of Avengers.
