Shani can do good for Vrishabha lagna. Even if Guru and others prove marakas, if they are alone they do not cause death. For those born in Mithuna lagna Ravi, Kuja and Guru are malefics. The effect of their conjunction gives adverse results. The Moon by himself will not cause death. The rest can kill. For those born in Karkataka lagna Budha and Shukra are malefics. Kuja and Guru are benefics.
