Russia — memorable quote from Axis Powers: Hetalia

“The Killer instinct is not perceived by words, but by look”

“Listen up, kid. There's one thing you need to understand. Human life is a fragile thing. So weak that I can destroy it with a touch of my finger. So watch what you say. If you don't, I may break something I shouldn't.”

“Fear is necessary for evolution. The fear that could be destroyed at any moment.”

“Tell you what… I’ll carve you up until you find yourselves cursing the fact that you have such resilient bodies.”

“Do you know what a scientist fears most in this world above all else? It's oblivion, my friend. A scientist measures our lives in the ways we develop and expand our knowledge through myriad variations. Nothing can take its place. It's our very soul. I have done the worst thing one scientist can do to another: I have altered your thought process. When my drug takes effect, you will find your mind has lost the ability to think.”
