What was Stalin like as a person?

Joseph Stalin was a lovable person, strong in likes and dislikes, he loved his country, he also wanted to contribute to the general well being and peace in the world! He was indeed a global person, as much as Nehru of India, Ner of Egypt! Some successors like Nkita Krushchev, learned a lot from Stalin's life and style of administration and political skills and wisdom!
