I see, that makes sense, considering Yamamoto's personality. But then I'm puzzled as to why simply stabbing someone through the centre of their chest would kill them, i.e., Unohana. Other characters, arguably much less durable, such as Rangiku, have survived having whole portions of their body being completely removed. I'd argue that such an injury is far more likely to kill than a simple stabbing through the sternum, where there are no vital organs.
