Ryujin
Legend
She doesn't implode *because of the alcohol*, though. The alcohol is presented as a result of her problems, not a cause of them. The alcohol is treated as "self medication" for her other issues, and itself doesn't get in her way - she never loses a fight for being drunk, does she? And I know a number of people who love JJ, and think that her hard-drinking is there to show that she's badass, because ability to hold one's liquor is seen as a sign of strength.
Those are the reasons why I think of it as being normalized - especially the hard-drinking as a sign of strength.
I tend to disagree. The drinking is there to show that she's broken. It makes her revenge hit that much more deeply. I have many of my own people to validate that interpretation
