The fate of the child

Written for the prompt:

Thor and Co break into Loki's lair after a suspiciously long absence. They find him with a crazed look in his eyes and the newborn baby that he smothered with his own hands, because he decided a quick death would be a kinder faith than whatever Asgard might have in store for it.

Takes place after all the times Odin and co have fucked over his kids.
