Well I would like to disgree on that comment, that is not the philosophy of hinduism there is not concept of infidels (by infidels I mean, people who dont believe on hindu gods) in hindu religion. Hindus believe all gods are one, people pray and name god, as Allah, god, ram etc. If you have faith in God irrespective of your religion, you are not considered infidel, your are just non-hindu
According to hinduism all humans irrespective of what their religions will be reborn according to their karma.
People with good karma like Mother teresa will attain nirvana and poeple like Bal Thakray will be reborn as suffer in their next life or may be born not as human.
