Consequences matter, very much so. However, they aren't the ONLY thing that matters.
So I'm curious what the ratio would be for you. Do you sacrifice 1 man for every 10, 1:100, 1:1000... etc?
It doesn't work like that. How about some storytelling? I'll go first.
Once there was small village on the alpine tundra. Everyone lived in huts made from the hides of animals. Freddo was a young man coming of age, and although truculent at times, was generally a well liked lad. Imango was another young man of the tribe, and he discovered the property of leverage one day, and soon learned how to apply it to pulley systems, thus enabling any fellow to be able to hoist heavy weights high overhead. One day, Freddo was in a particularly cantankerous mood, and most everyone avoided him, except for his friend Bitkish. Feeling industrious, they built a sort of gantry made from tree limbs over the village's tribal tent. Then, using a pulley system and some frayed ropes, they hoisted the heaviest boulder they could find (rolled down from the hill above), until it hung very high above the tribal tent.
Ayoo, the tribal leader, cast his eyes upon the threatening and rickety structure and asked, "What is this?" Freddo, so proud of his accomplishment, said he devised it as protection from the shaman leaders, who demand that he spend each day either hunting or tilling the land. Ayoo, wise in his ways, called for Freddo to lower the boulder immediately. Freddo, getting ever more pugnacious, said he would do no such thing, indicating that there was no reason to, as nobody was injured, and unless someone was injured, why should there be any reason to lower the boulder? Bitkish, hunkered down behind some animal hides hung out to cure, snickered as he listened in.
Just as Ayoo was turning to discover who was skulking behind the animal skins, the frayed rope broke, and the heavy boulder crashed into the tribal tent, then tumbled down the slope, rolling onto Bitkish. Freddo shrieked, not believing what he was witnessing. Ayoo ran into the remains of the tribal tent, and discovered two injured shamans, one the blood father of Freddo, although Freddo did not know this, as he was raised by Thescripto.
Ayoo banished Freddo from the land, sending him on his way with nothing but all his worldly possessions, which were a spear, a leather skin to hold water, and the animal furs he wore. All the while, a hawk, perched upon the highest point of the gantry looked on, seemingly wise and all knowing.
