And yes, some people do argue that since it was seldom/never shown on panel Thor was just being naive, having founder memories of his youth than the moments really were, that what we saw was all Loki ever was, or anything along those lines and that they still don't think it makes any sense.
Yeah, Iron Man did some dickish things and Thor was pretty angry. But in the long run, Thor forgave him because the years of friendship he had with Tony out-weighted the period of time when Stark was being a dick in his eyes.
It's KIND of the same thing, in that Loki and Thor grew up together and were likely on good terms for the vast bulk of that. To gods that might be centuries. So the recent years where Loki is trying to kill Thor in contrast to the length of time where they were family from a gods perspective might be comparable to lenght of time Tony and Thor were friends in contrast to the period of time they were enemies.
I think it's Volstagg
