[MCU] (Endgame spoilers) Why is Thor cool with the fact that Valkyrie basically used to work as a human trafficker for a sadistic space dictator?

It's one thing to be depressed and want to drink your sorrows away, it's another to cope with your past by kidnapping people for a sadistic dictator knowing that they're going to be forced to fight to the death in an arena for the sick, bloodthirsty amusement of others. Valkyrie has innocent blood on her hands and must've ruined a shit ton of innocent lives before she suddenly decided to be one of the "good guys."

Her job before she met Thor is something that only a person who is straight up evil would do. And not only does Thor decide to befriend her, he decides to make her queen of Asgard? How would you feel if you were an Asgardian whose kid died because they were kidnapped by the Grandmaster while vacationing on Sakaar, and now you find out that the woman who kidnapped your kid for him is now your queen?

Given how Thor behaved in his youth, how Hela behaved in her earlier days, and how Odin behaved before Thor's birth, having a history as a genocidist or a war criminal doesn't disqualify someone from the Asgardian throne. Looking at that list it may actually be a requirement.
