the espers were "raised" by this asshole family. Even the earrings they have are probably a way to neutralise them if push comes to shove. They probably experimented on these espers, then, built the only thing that can tame them: guides, and this family has absolute control over both. So, it does make sense that espers cannot revolt because the family most likely has a way to blow them up. The third platoon that MC was the captain of seemed strong yet they got rid of them like they were nothing

Humans with supernatural powers that could kill any ordinary person within seconds get treated like trash and thems Espers just let it be done to them. Mhm sure, makes absolute sense. Σ(  ̄□ ̄||)
