fathers death

Can somebody by just looking at the birth chart predict death of father?

No. Some astrologers think this can be done. Some astrologers claim success, but with a fairly advanced process. But there are too many predictive failures to make this a worthy pursuit. Some astrologers believe that death prediction is unethical, notably for the death of someone other than the querant. I can itemize some of the major issues and predictive failures upon request.
