you obviously don't know how wealthy families work. when a child soes something stupid like cut off your own dick or in this case chemically castrate yourself, the executor of the estate will entrust funds to the other 9 kids. the 10th one that is mentally ill will not get funds or at least authority to manage any capital put of the family trust. the other kids might feel sorry for it but at the end of the day that individual is completely put of the will.
