“The Lady or the Tiger” Which Door?

In the story, “The Lady or the Tiger?” by Frank R. Stockton, the man opens the door and see the tiger. The princess had found away to stop the man from picking the door with the other women in the other door. The princess was jeluse which it said in the story, and who wouldn't be, known that the man you love may have someone else to hold. With that she did not want to see him with her so she ended his life with out him even known what was going to happen. Also she found out which doors had what for a reason and I believe it was so that she could do her little evil plan to stop him from opening that door.
