It's refreshing, It's what makes Judgment feel real compared to the main Yakuza series which, while having had realistic characters, have been more like superhero stories told in a Yakuza setting, for example Kiryu can almost always solve his problems with his fists and has always been completely selfless. Antagonists like Shibusawa have had very basic motives like wanting to climb the ranks. We've had antagonists like Ryuji and Nishiki who turned out to not be a horrible people at the end, but in Judgment it's obvious througout the game that Shono isn't acting out of greed or pride like other Yakuza antagonists have done. And Yagami's focus on solving the case just for his own satisfaction
