in my persepective child born without known father wii have no successful life. He will be depressed in his career. University, employement, traveling or other such events people will ask about his father and when he will reply with that i dont have father most of the people will laught on that or will look strange to him especially if he is asia, gulf etc.But still since a child has no role in such birth may be he will be good if properly educated, treated and cared by parents, teacher, guardians. But this does not mean that we should encourage such births as it has a lot of other problems also which affect society.
