yes, the evil eyes are a downgraded version of the capital sin's demon series and they cover the rest of the senses as far it was implied, as an example ursh had the eyes of mammon, but the second prince had the ears of (the same) mammon until ursh's plot that involved res said prince to become THE king of greed, removing all the other senses from their previous hosts and the posibilities of these being hereditary again BUT the evil eye related (that also changed but not outright deleted); he didn't to do harm, in fact the arc was about helping said prince prevent ending mad because, like ursh, he cannot stop hearing the constant influx of the other's thoughts
