Kriones

I am outlining for a novel (something I've never done before with any success) and it's set mostly in the country of Rinadrion, a very warlike country. Part of the plot has to do with a small percentage of the country's inhabitants who are deridingly called Kriones by their fellow countrymen. So, what exactly are Kriones?
If you'll remember from my post about Rinadrion, there is a small, mostly isolated group that have gone to the opposite extreme of trying to invade and take over every other country in the world, and are pacifists, shunned and ostracized by their countrymen. Krione is taken from Kriona, the goddess of peace, prosperity, and comfort. Basically, they're being called cowards.
The character in my novel who is a Krione is not a full pacifist. He is conflicted about what role violence should play in a man's life; whether it is fine to kill in self-defense or to defend one's country if it is invaded.
As you can see, something like this has the potential to be really interesting if explored. If you'd grown up in a country like Rinadrion, yet realized there was something wrong with their constant warmongering, would you go to the opposite extreme and become a pacifist? Or would you be really conflicted, not knowing if you should kill, or what the right reasons for killing were?
