Recently someone posted a video on Mars + Ketu combination as Pisaach yoga, Now let us try to understand the meaning of the Piscach word - The literal meaning of the word is devil creature, but when we think of human nature when a person does something violent and against the acceptable social norms one said to be of Pisaach पिशाच प्रकृति, Jamini has mentioned three sutras in the Stri jataka chapter related to Mars and Ketu combination and its influence on the 7th or 8th, Jamini mentions that in such a condition the said lady can in a fit of aggression harm or kill her partner ( sutra 49-52) Stri jataka ( Jamini sutras by Dr Suresh Chander Mishra).
Further, I wrote two articles one for modern astrology based on the above sutra and one for Express star teller on murderers and psychopaths, Mars + Ketu in a chart does show a violent reaction to a situation.
