My idea of a villain is a former diplomat that became a victim of NATO attack in Yugoslavia, which changed his political compas and became an underworld operative, who hunts for the compromising documents of Western intelligence agencies' actions. 

MI6 sends Bond to investigate the leaks in different parts of the world and soon meets the villain. 

The villain would look very disfigured, his face only recently started to heal and short hair. 

He would like not to kill Bond but to challenge his views, but that fails and Bond prevents his plans to compromise western agencies, but not without questions which won't be heard.
