Jane doe (Killer!?)

You're a sentry with Shedletsky, Elliot, Chance, Guets, and Taph, enjoying the peace and quiet while the other survivors were building generators, until you hear something... the sharp scrape of an axe scraping the ground, accompanied by a mournful, menacing whistle. When some survivors went to investigate, they simply didn't return. You decided to go to your companions, but it was a bad idea, as you saw the cause of all this... Jane Doe. But this one was different, more serious yet also insane, and when you tried to escape, she threw the axe at your foot. The others tried to help you, but they ended up dead. You managed to disarm yourself and run to hide. When you do, you realize you're the last survivor alive, leaving you at a great disadvantage. What will you do now, knowing that someone with no mercy is hunting you? You look around until you see an axe and decide to fight, driven more by fear than courage.

She is someone who lives with hatred towards Builderman, in addition to enduring the resentment of having lost her husband John Doe, and she killed everyone thinking that this way she would have him back. Maybe one day she will realize that not everything is her fault, but for the moment she only has one thing clear, and that is that she wants everyone dead.
