We are peaceable out of necessity, and because of it we are the most powerful race in this galaxy.
For a Human to kill another takes but a moment, a sharp knife or even just a few ounces of pressure and a man can be easily killed, his corpse discarded as a worthless sack of meat. Indeed, if there has been one constant throughout Human history it is that we have always found new and more creative ways to kill one another, ways to kill one another more quickly.
We invented the spear, the sling, the bow and arrow, the cannon, the musket, bombs and nuclear weapons, out latest achievement is the power to simply snuff out a star thus condemning an entire solar system to death.
We are a violent vengeful species, yet throughout our wars and bloodshed ever evolving we spawned another weapon. Honor, brotherhood, a place to belong, and a reason to fight.
Once we fought to feed our bellies and rut with our mates in the dirt, and we still do on occasion. Now though, we fight for grander ideals. We fight not for ourselves, but for those whom do not whish to fight and those who can no longer fight. The bonds we form with one another, those not of our lineage whom we call brother and friend, it is not a pact we enter lightly nor one we toss aside with ease.
The Yunik of Mordanin were perhaps the most powerful species in this quadrant, indeed on our first encounter with them in deep space out ships and troops were easily dispatched and destroyed in gouts of plasmonic fire. Like in our past we held our hand out to them in kinship, as Humanity has done for every enemy in history. We do not wish to march towards war, we would rather have our pacts and vows ring empty in the air.
The Yunik laughed, saying they did not need a friend. Indeed even amongst themselves the Yunik were a violent race, much like the entities of every other race in these chambers. Survival of the fittest, every single culture here is based on that principal except my own.
The Yunik faught within their own ranks constantly, the strongest was the leader.
The Ryin follow much the same principal, if only more subtly poisoning and forming temporary pacts only to betray one another for personal advantage.
The Hicloo literally absorb their weaker peers, taking their memories and experiences adding it to their own.
Every race in this quadrant is constantly at war not only with everyone else but with themselves. Each member of the race only cooperating for their individual benefit, their individual advancement.
So yes, Humanity is the most peaceful species in this room.
We do not stab one another in the back, we do not fight for ourselves. We fight for those whom do battle beside us, and those who are behind us. The Yunik did not understand this, and for that error they paid the price of meeting on the battlefield an enemy that did not waiver, and through sheer force of will destroyed them.
The Yunik are no more, for the simple fact that Humanity has weaponized peace. We fight so that we might return to peace, return to our brothers in arms, and to our families. With our weaponized peace the more you try to fight us the more powerful we will become if only to return to it.
So I ask this assembly, who among you is willing to make peace with Humanity?
