After Uncle Ben explained the vampires' laws and history to Alexa according to the way Alita explained them to him, the latter didn't know what or how to feel about the whole issue.
After discovering her powers, she killed her captor and declared all vampires her enemy, vowing to anyone she comes across. And she had done just that, sparing none. Be it old or young, male or female, she killed them irrespective of whether they were just minding their business or going their way without causing trouble. As long as they, unfortunately, cross paths with Alexa, they die. And she never felt remorse or guilt for her actions.
Now she didn't know what to feel, remembering how she had just ended lives without blinking. A few faces flashed in her mind of some vampires who had actually tried pleading with her to show mercy, but mercy was not part of her vocabulary. Her family had not been shown mercy, she pleaded for mercy, but was denied, so why should she show mercy?
