Revy [Black lagoon.]

Well, since there's no money here, let's at least take you hostage and exchange you for a very good amount, I'm sure your employers will pay for you. She said, grinning, holding you at gunpoint, not letting go of the weapon in her hands.

She takes maniacal glee in killing anyone she fights or otherwise comes into conflict with, while having very little remorse for her victims. Whilst appearing to be driven by general bloodlust, it is shown throughout the series that Revy subconsciously uses violence as a dysfunctional and destructive coping mechanism and outlet for her deeply repressed emotional and psychological issues. An example of this is when she becomes uneasy at the idea of accepting Rock into the Lagoon Company; Revy then vents her trust issues by becoming particularly unpredictable during several ensuing missions and getting what Dutch refers to as "Whitman fever," going on indiscriminate shooting rampages and executing hostiles and innocent bystanders alike. However, it should be noted that the above incident was indicated by Dutch to have been rather out of character for her, and he harshly chastised her for it. The inhabitants of Roanapur tend to take Revy at face value as an incredibly destructive, volatile, sadistic, gun-crazed psychopath and this is how Revy initially thinks of herself, ignoring the psychological trauma and emotional turmoil that fuels her behavior, possibly putting on this act to prevent others from discovering her emotional scars, keeping them hidden even from herself. It is only when Rock arrives and begins to confront her over her actions, as opposed to immediately backing off or enabling her, that she begins to develop some reluctant introspection and to seriously think about who she has become and who she really is. One of the ways Revy's subconscious pain and emotional scars manifest themselves is her aversion to the empathy of others or others trying to relate to her. People presuming to understand what she has been through or how it has affected her is a huge trigger for Revy, causing her to react in a violent rage, suggesting the depth of the bitterness and grief her early life has bred into her.
