i really appreciate how this volume, how this take on the character, isn't afraid to talk about laws, how an individual like Deathstroke uses the law in favor of himself and how the comic points out flaws in the law system and the difference between justice and vigilantism. plus, the confront with Superman is not about brawls it's about different ideologies and world views, this makes Slade more tridimensional as a human being, he feels like a(evil)person, not just a piece of paper.
The comic also explains the origin of Slade's group of mercenaries and the origin of his sword, which is appreciated
but my favorite part is the criticism of gun violence, this is actually a deep and thoughtful look into the problem, taking no sides, only the facts and lefiting to the reader to decide what to think
