Yes the series is a very interesting one. The fact that it is based on true events makes the series much more captivating. The idea of the legal system hiring criminals to do very dangerous work in exchange for leniency is something that we see a lot in movies but this series proves that it really happens.
There are definitely levels to criminality but I agree that no sane person can just become a heartless serial killer. It takes a special type of monster to commit such acts and still be able to live with themselves. Black Bird does well to show us a bit about a serial killer. It's difficult for us regular people to understand why they do terrible things and so the natural thing is to hate and be scared of them.
Thank you so much for reading my post and for the comment. Have a great week ahead!
