The correct answer to this open question is the following.
If the leader you chose was Mohandas Gandhi, then let's talk about him.
Mohandas Gandhi was considered by some people as a villain because many people died and many others spent time in prison by participating in the movement organized by Gandhi.
Another argument is that many people think that Gandhi led the conspiracy against Bhagat Singh, and finally, he was killed.
Finally, another controversy created by Gandhi was the selection of his heir. He chose his successor in the person of one of his closest pupils, Nehru, when many people believed that Sadar Partel had more experience and skills to become the leader.
