It is not President Kalam who directly takes the decision. When he gets the petition for clemency, he sends the same to the home ministry for evaluating the merit of the same.
Only after the reply from the home ministry he can give his decision which is the set protocol. And as we all know who controls the home ministry.
The congress spokesperson has even gone as far as to say that on an average the entire process of granting clemency or executing the person takes 7 years in India.
So rutuja It has nothing to do with the religion of President Kalam.
