I know it's late, but what evs.
Kingdom is one the most gory manga out there, with people seemingly can be cut like butter by a child soldier (though I suppose Xin's sword is a named sword?), but unlike any popular edgy/gory fiction that fond to butcher their characters, Yasuhisa Hara rarely kill named character out of the blue without purpose. Mostly, named character deaths are related to the plot, and character development. Kingdom is 399 chapter in, and the only named member of Hishin unit that die was bucktooth's brother IIRC. Qiang Lei, not only a major character in Kingdom at the moment, (s)he's also a future general that will lead the invasion of Zhao historically along with Xin. If she's gonna die, Hara will make it proper and not a random death.
I don't really find kingdom all that gory honestly. It gets so cartoony at some point that all the gore loses all of its impact.
