Thor has already forgiven Loki. In Avengers, he's practically begging Lil' Brudder to just come home and everything will be all right. And even though Odin will likely be righteously pissed that Loki tried to murder him and all (or at least get Laufey to murder him), he might have just enough guilt within him to try and give Loki a second chance.
