If Basim is Loki post Ragnarok, let's just all realize that all his kids are dead. He's waking up, alive and a new person, while his kids are dead. Not only that, but in AC valhalla, when the MC wakes him up for the first time after he was trapped in that false valhalla by Eivor and Sigurd, Hytham is dead. An from what everyone is sure to know, especially during the "saying goodbye" quests, is that Hytham and Basim were practically father and son. Even Basim while listening to Hytham's little speech gets a bit emotional. Now he's stuck in modern day America, attempting to "save the world" as the game seem to imply. That's not even mentioning that Basim himself before awakening as Loki literally had his whole life torn apart. His "family" also died. He was betrayed by his mentor. He found out his best friend was a hallucination of basically himself but is more Loki. Even his eagle ends up disliking him.
