It does clearly lucidate Vriska's actions.
This changes nothing about my interpretation of Vriska, save that she now thinks she succeeded in playing the game well.
I think I know what's going on.
Hussie made everybody start going on murder sprees to make Vriska look better in comparison.
And then to top it off, after he shows a bunch of merciless murders, we see Vriska baring her soul.
"Yeah, she murdered Tavros, but she regrets it. So at least she's not as bad as Gamzee or Eridan."
No, AH started with Eridian and Gamzee on killing sprees because that was damn well predestiny.
These trolls were always going to kill each other. It was only a matter of who done it.
Spades slick, Vriska, and Aradia all achieved god-tier for killing.
Also, she may regret those things somewhat, but as it seems to have brought her to power and destiny bullshit, so she doesn't regret 'very much', save killing Tavros.
So basically Aradia and Vriska are reverse peter-pan. They grew up into hardcore trolls.
Eridian and Gamzee are doing pretty good too.
It seems to me that Eridian and Gamzee are either going to have the most dramatic fight ever, or join up and become best buds. What with Gamzee's insanity, probably the former.
