Please keep in mind that all persons having the initial letter “R” in their names are not Radhikas. Radhika may be a good industrialist or a doctor. That depends upon her education. Like wise all the planets have some portfolios to play according to their places and other factors.
As you asked clarification Saturn is atmakaraka in one chart. Saturn is a malefic. But Saturn is a benefic also. Everyone can not exist without bones, teeth etc, as Saturn has control over bones, teeth etc in the body. So Do you consider Saturn as a malefic or gives pains.
We have to take not only nature but also all the other factors. Hence I advise you to give the birth details and discuss.
