If Daud surrenders with his money,wealth,arms&prays for clemency before the President,is it posible to forgive?

Some years back, I read in a local newspaper that once Daud expressed his willingness to return to his motherland, that is India, on condition that he may be given clemency. I don't know whether this report was true or false. But it is a natural desire for every human beings to return to his own motherland, where he or she has spent all his moments of life starting from the childhood days, teenage, and youth. Someone's past or present life may be related with crimes, but among them, few have also a desire to lead a normal life where no one will hate him or fear him, but he or she will be accepted by the society and loved by the people, and he will not have to live a life in isolation from the society or the country. I have seen that Abu has been returned to our country, and he is now in the jail, and he is wishing that someday he may be released from the jail and live a life like a normal man. But here the question is that many lives has been expired due to their past crimes. And the people who have lost their near and dear ones, they may want and try in every way at every stage that he may be hanged by the court of law. My question is simply a legal one. From the legal point of view, is it possible that even after such high crime records, if he desires to live a normal life returning to India, and prays for forgiveness before the President of India and be prepared to live some of his life years behind the bar, is it possible that he may be pardoned under the Indian Penal Code and Judiciary system?
