Kars' attempt to "better his race" came off as more of a crazed plan to the other pillar men, and it would disrupt their way of life due to the increased hunger that Stone Masks bring upon. So Kars wasn't really bettering his race, he just thought he was. And pillar men are very intelligent, so we can assume that the tribe wasn't being very irrational.
