Maybe so that we’d get more understanding of his character?? I don’t think the author is trying to redeem him all that much, but is showing us why he ended up being such an asshole. What he did to Dan isn’t ok but we can see where his btchass personality comes from.
True
you're joking right
Like, to write a good story and give further depth and explanation to a seemingly complex character. . . Just guessing. . .
I personally don't need his backstory to like the character :DD
I dont get why author bothered showing his background and past at all
