I think there is a story in ?? about a Ger Amoleki who Dovid Hamelech killed. There is some sort of ?????? ??????? if I remember correctly if an Amoleki can become a ??, and they bring a ???? from this story that he can become a ??, but will retain his status of Amoleki.
According to that, a ?? who from ???? will be ?????? to kill himself, because he will be ????? on ????? ????.
