I don't really like any of the 1p's, but if I had to choose one, it would probably be............Denmark, maybe? He seems like a pretty cool guy. He can definitely wield a weapon. That battleaxe of his is pretty bad ass and I wouldn't mind being his ally.
As for which nation I would like to kill, that's a harder question. Almost all of them are either annoying, crazy, emotional, or strict. I wouldn't mind killing Austria, as he annoys me. Although if I had the chance, I'd probably kill Spain. He's too happy and I want him to feel pain and sadness. Even better, I could kill Romano, so then I can get rid of one of the countries that annoys me and make Spain depressed at the same time. Two birds with one stone, baby.
Next question.
