Vriska believes that bad things constantly happen to her because she has terrible luck. Kanaya Maryam and Doc Scratch suggest that her own behavior is more likely the cause - for example, she constantly steps on d4's only because she leaves them all over the floor instead of tidying up. She also seems to hold some degree of distaste towards her own blood color, mockingly referring to it as "enviable cerulean swill" - just another thing for her to blame her problems on. On other occasions, though, Vriska holds herself in high regard - she often brags about her exploits in Flarp, or just about herself in general. While she sees herself as a great manipulator, it seems that she is often manipulated herself, as clearly evidenced in Doc Scratch's final conversation with her. Although she would loathe to admit it, she envies Terezi a great deal because of Terezi's ability to manipulate people without the use of psychic abilities. This could be a possible motivator for Vriska, as she attempts to trick, deceive and backstab nearly every other troll - perhaps as a way to prove herself in Terezi's view or even in her own. When another troll calls her out on using mind powers, she either denies it to the point of absurdity or throws a tantrum.

Despite all her negative traits, she does have a softer, more benevolent side. She was genuinely upset when her plan to reconcile with Aradia failed, and she also has admitted to John that she felt bad about killing Tavros and that even though her methods were more than questionable she did genuinely try to help him get stronger. She also mentions to John that one of the reasons she wants to fight Jack Noir is to protect her friends.

Vriska cares for her friends more than she usally admits, stating to John that protecting them was her real reason for planning on killing Jack, not just glory. She was known here to get angry at Jack for killing Karkat and Terezi after seeing their corpses in a doomed timeline.
