It will not matter. Once you are branded a villan in this day of social media where basically the idiocy of the crowd comes online, then it takes a massive event to change it and even then it dies much later. Modi is not the monster he is taken in the form of, he is a politician and politicians are first and foremost loyal to their seat. A seat the comes from votes, if those votes come from the support of people who want genocide of Muslims then he will oblige regardless of how he feels about it. His goals are more that of a businessman and he would have no qualms in wanting to end this pointless bickering between India and Pakistan.. but he is a politician first and will do what the people ask and NOT what is best for them.
