My favorites would probably be Jeff The Killer and Jane The Killer.
To me, Jeff's story, or the version I read of it, is very sad. He tries to save his brother Liu from being mugged by these kids, and ends up killing one. To me, it's just self-defense, so he could've done it and it would've been legal. He soon goes insane by one of the fewest known instincts of the brain taking over; Kill.
While Jane was just a victim, I don't think she truly or fully knew Jeff's story, only knowing he must be stopped, and eventually ended up trying to kill him whenever she had the chance, not to mention stalking him and playing mind-games with his already broken mental state.
I think in the end they'll both die, knowing that there's no room for these confusing beings of both darkness and bravery. Don't worry; They're fight will always remain with themselves, and if Jeff tries to kill you, you can always count on Jane to eventually avenge your death, or maybe even save your life. Just remember, Jeff does not mean it. Blame the children who started this mess, the three kids who tried to mug Jeff and Liu.
