@ZeroWWE Victims will often become offenders themselves. While it wasn't handled great in this chapter its perfectly reasonable. If you just google it you will find plenty of talk on the subject.
The logic goes something like "I don't want to be the victim so ill be like them" Its a little more complicated but basically its just a response to being hurt and seeing it as a choice between being the one hurting people or the one getting hurt. Its not exactly logical or anything but it is what happens.
Instead of being prey they would rather be predators so they no longer feel weak, powerless, helpless etc. Again not handled great but she clearly wasn't ok. The biggest problem was that they were sexist and Leon never got the same treatment. He should have showed some signs of this but instead they just treated him like scum.
