Duryodhana and Ravan: Who was better ?

Sanjay :
Both were evil.
Ravan was a rapist.
Ravan took Lanka away from Kuber.
Ravan kidnapped Mata Sitaji.
Ravan did not listen to the advice of Vibhisan and dismissed him.
Ravan did not respect his grandfather Malyavan.
Ravan did not listen to any advice from his Sati wife Mandodari.
Ravan would not listen to anyone and continued the battle with Sri Ram.
Ravan ignored the peace prospal by Sri Ramchandrji.

Duryodhan did have Draupadi brought in by Dushasan and tried to treat her badly.
Duryodhan treated Pandavs very harshly.
Duryodhan listened to Sakuni and not others and continued the battle with Pandavs.
Duryodhan used to disrespct Bhisma, Dorna, Kripa and Vidurji.
Duryodhan ignored the peace prospal by Lord Sri Krishna.

Good behaviors.

Ravan was a great bhakt of Lord Shiva. Ravan prayed to Brahmaji also for boons.

Ravan was known to be a great bhakt of Lord Shiva, while Duryodhan being a bhakt of any Dev is unknown. Yes, as a rapist, I do consider Ravan worse than Duryodhan.

Ravan also had his army of Raksases kill lots of Rishies and destroy yagnas, while Duryodhan performing this type of deed is not mentioned anywhere. This is another factor that shows that Ravan was more evil than Duryodhan.
