I was watching the Lakshyagrah episode today and despite very clear hints from Vidur and Bhishma about imminent danger in their travel, he just brushed it off. A good ruler would consider all possibilities and usually opt for one that causes least damage and maximizes benefits for all and since its Yudi, is compliant to dharm. I would have liked him to ponder about the hints and decide rationally. He just saw Kunti emotional and took a rash decision I felt.
