thats for magic hes a magic tuto not a how to die or ruin yo life advisor and it seems more like the father just want more power for fam and that's ok its normal for nobles in manga to strive and make the family stronger but then in this case the father is 60% wrong for this while the brothers 40% wrong but lets say he does have to lisent to everything the tutors says (he doesn't) why dafuq would he believe him and don't get me wrong ik he a kid but like who u known longer yo brother or yo tutor like obviously you know your brother better so howdafuq u believe him and this was even before the brainwashing stuff
just kill the brother already and kill tht father to just because the father wants more "power" and shit honestly what a shitty family except for the sister and the servants tho they nice to the mc the rest of his fam and that damn instructor tho just kill them ://
