darko82, Khan is fun, many "not nice" leaders as you say, are in fact fun and interesting, Ghandi is just annoying, plain and simple. Deal with it. Comparing him to Genghis and other great conquerors is beyond ridiculous.
No, that reffered to the argument that he is not a nice person as if other leaders were nice people. You miss the point. Those arguments are simply invalid.
For you he may be annoying; for others fun.
