Kind of?it's like an S class in the novel was always described as people who were a bit abnormal in a sense,like the author always tried to say that an average ranker A-F rank tho they themselves have a huge rank difference,S ranks were just born different,A ranks wouldn't even compare and within those S ranks some were more different,like those with a potential to reach SS rank.So,yes that's the case,they have killed more before.Botg sides aren't truly good id ur asking

i have a question for novel readers
is the reason for killing the nurturers of the previously eaten worlds because they would rather protect the nurturer obsessively rather than the world??
