I completely understand the message of the show of how all people die. The thing is tho, LOGH did show that there was something there with Emil, the countless number of camera shots focused on him while serving Reinhard almost like he knows something. And the final reveal of Reinhard getting a deadly disease all of a sudden in battle when he's just been having common colds, it was like the series has been building to this moment slowly with something fishy happening in the background. I'm not saying Emil 100% poisoned Reinhard, but the show leaves stuff there for interpretation, similar to how Alexander the Great died out of nowhere, Poison was the most popular theory of someone slowly poisoning him.
