Laufey didn't even know you, he had no reason outside of being a bad person. There is nothing you did to cause that.

[ Thor has a great deal of disdain for Laufey, that's one of the major reasons. Cruel from the start. ]

Odin had three children and unhealthy relationships with all of them. At least part of that is on him.

[ It's not favorable odds for the King. Thor is not prepared to put all of the weight on their father, but some of it, perhaps. He did treat Loki poorly, they had proof of that. ]

I'm not saying you are an innocent snowflake, but you mustn't base your worth on two flawed individuals.
