This may be an unpopular opinion but the Norse gods aren't the best characters either. Don't get me wrong I believe that the Greek gods (especially Zeus) are much worse but the Norse frequently go back on theire word and break promises. Examples the giant that built Asgard didn't get what he was promised for the work, neither did the dwarves that made Odin's and Thor's weapons (granted the dwarves wanted Loki's head but still) and there's a lot of evidence that shows that Odin knew about baldurs death and didn't to anything about it.
okay let's be real: Vali is a battle maniac not a suicidal fool - he would want to fight Mark but not to the death. Also I don't think Albion would want to join Mark because 1. he has been with Vali since he was a kid so that has to mean something ; and 2. Mark already has Ddraig's powers and he hates Ddraig
