I suppose with the presence of Pokemon and their eagerness to defend even those who don't need that defense, such skills are less necessary...

I don't understand how practicing killing could be a game. Can you explain?

[To Lupa guns are weapons and what you do with weapons is kill. That it doesn't always result in death doesn't matter so much as death being the entire purpose of the weapon. Of course, he doesn't see anything odd with the idea of being rewarded for success at killing either...]
