so what you are saying is that child Loki, this Loki,
has already killed Balder among other terrible things done and done to Loki in the myths (depending on what exactly they include in MCU)? Is that what you are proposing?
or perhaps the baby did it?
and then everyone up in Asgard just forgot, or forgave him because he's just soo darn cute.
and not only that, per the quote from the film book from earlier...
"Loki was a shape shifter that could turn into anything he wished. He was far more spiteful, cunning and deceitful than the other Gods in Asgard, which often led him into trouble. Trouble would be created because he loved playing mean and deceitful jokes on others. Eventually, he was seen for what he was and was distrusted. His quick wit and honey tongue inevitably caused the Aesir to forgive him which left room for his role in engineering the death of the god Balder."
So that would lead one to believe that this version of Loki pre Thor 1
has already done terrible things and been forgiven numerous times and then killed Balder at some point in time, child or not, AND not only the midgardians know about it, but all of the Asgardians must too. They have already apparently forgiven him for that terrible crime enough for Thor to treat him as a brother and Frigga and Odin to still consider him a "son" and potential heir to the throne by the time Thor 1 comes around. Nope. that really doesn't make any sense at all.
"Loki's always been one for mischief but this is something else entirely." ~ Fandral Thor 1
To this proposition that this version
of the characters have done what the myths say already - I say NAY!
It is clear to me that either it will be that the midgardians made everything up about these "gods" to explain things, which is what happened with real mythology anyway, or it was based on a previous version of them that some stories had come down to Midgard (think the Telephone game) over time, with some variations and changes depending on what stories the Norse wanted to tell.
I am leaning towards the second explanation, which is actually supported by the book quote, for the reasons stated, but also because the death of Balder is a precursor to Ragnarok in the myths. So like I said, the Norse Myths in the MCU are very likely going to be based on previous incarnations and previous Ragnarok.
The question is, Balder is mentioned in the MCU now per this book, but he does not appear to be in the current version, so where is he? Or will they completely ignore his part this time?
