when all the asguardians died after Ragnarok & thor slept after killing the ones who sit above in shadow
when thor came back he was able to resurrect the fallen asgaurdians trapped in the soul & bodys of humans. so yes loki tricked him into killing Bor but by these rules (especially since he was an all father)
Thor's grampa should be in a human right now why isnt thor searching to resurrect him? or his to uncles...
or am I missing something here?
