Also, are koloss just naturally bad-tempered, even without Ruin’s influence? Cause the koloss are still taking swipes at Sazed immediately after the merger. (And, does Sazed zap all the koloss? Did they all get toasted by the sun? But what about Human and his friends underground? Are there still koloss around? Just wonderin’.)
Koloss were bad tempered before Ruin’s influence, though he certainly made them worse. They were designed by the Lord Ruler to be aggressive, so aggressive that they would destroy themselves if they got loose and away from him. (This was intentional. Note that he didn’t give the spark of humanity in them enough credit, and they managed to overcome this and ‘evolve’ in a way to keep their species going, even after he died.)
There ARE still koloss around, though many of them were vaporized. Human is alive. Sazed took pity on them, however, and they have been transformed. They are now a race that breeds true, like the Kandra, and have different thought processes from what they once had. You’ll see more of them in the sequel series.
