Not military? Ah- I keep running into soldiers, lately. [And a military man might have cause to keep a purposefully lax mindset when it comes to death, so he might have assumed without the mercenary reveal. A mercenary, though... Tenma gives him a glance up and down, like, huh! Takes all kinds!]

Do you really think being a doctor makes death "normal"? I took an oath to save as many lives as I can. Should I really give up on my patients because they're going to die one day, no matter what?

[that pork platter better not have any nihilism in it, young man.]

Death is always a tragedy.
