Kishimoto truly hates Sakura.

Ever thought it's because Kakashi had a MS before and mastered it in the years he had the Sharingan while Sakura have no experiences with using a doujutsu? You think Sasuke is going to expect them to wait for Sakura to learn how to use the eye to break IT or do you think they'll give it to someone who have some experiences with using a doujutsu and would take less time to figure out how to use the Rinnegan?

Because Kakashi knows how to use Rinnegan, right?

He refused to give her his seeds why would he give her his eyes.

LOL, sakura is not suit for that job

Why wouldn't he be able to?

Sasuke literally knew how to use it without any prior experience.

Going by your logic Sakura and Naruto would know it as well.
