No one knew that Rana is hiding this much animosity and ambition within him. All his peers only knew that he has no standing in the family, at least as big as the one Gnyan had.
But it seems like that he is more than what they thought he was.
Rana agreed to Fidi's proposal not because he wanted to get his father's attention when he understood Sam's characteristics and the consequences of his actions, he didn't want to use this to propel his position, he wanted to destroy his brother's standing first.
He only targeted the betting section this time, but Yodha's actions made his job easier.
He lost all the compassion towards his peers in the family, his father, and the elders.
The time he was dropped into the Arena he decided to make sure that he would destroy all the chances for the family and make himself the only choice as the family head. Unless they can kill him without a care in the world, they can forget about letting other candidates have a shot at the family head position.
