The thing is ayanokoji saw anybody useful as tools and for them they think that he also saw them " who think they above him " as tools and hurt there pride.
It's understandable that ayanokoji sees people as tools. I mean he grew in a white room where they see useful people as tools bc of the torture(?) he experienced (and if your a ln and anime reader/watcher, pls correct me if i said something wrong bcz i haven't watched the anime yet or read the ln, its also bc I'm lazy asf)
fun fact the person you put ryota future as went in a VERY harsh acadmey for kids or orphans where they train you to be hearthless and some people lose there emotions while in there and only he survived it others got hearth attacks
