In data book three, it says in her profile that she was the sole survivor of a burned down village. Orochimaru found her, asked her how she survived and took her with him to his hideout. There, she helped Orochimaru with his experiments. Long story short, her data book says Orochimaru decided to bring her back to his base because he felt that Karin could get closer to Sasuke. After learning this bit of information, the first question that popped in to my mind was why? Why and how could Karin help Sasuke?
Here’s what I think. Orochimaru knew that Sasuke had isolated himself emotionally from everyone who had ever loved him after the massacre of his clan. Sasuke became emotionless and filled his heart with hate. It was only after he graduated from the academy and joined team seven that he learned how to feel again. After he received the curse seal, he closed off all his emotions again so he could purse his revenge. He abandoned all his friends and his entire village so he could get more powerful. So what if, Orochimaru figured Karin being an orphan and having lost everyone she had ever cared for, would perhaps have the ability to understand Sasuke’s pain/grief/emptiness and loneliness.
Let’s say, the reason why Sasuke cares/respects Karin is because they share a common pain. They both know how it feels to be lonely in the world and to feel hate towards the people who slaughtered their kin. So, if Orochimaru’s plan was achieved, Sasuke was able to bond with Karin because of this. I’m not saying they’re the best of friends but I’m just saying they might have healed each other’s wounds slightly. I mean, I think that’s what Sasuke has always wanted, someone to hear him out and understand his reasons for pursuing power. He wanted a comrade who wouldn’t judge him or stop him from gaining revenge against his brother. I think Karin might have promised to help Sasuke beat his brother a long time ago because they bonded over their similar backgrounds/situations. So, when the time came for Sasuke to form his team, he sought out Karin because of her amazing abilities and for that small bond they shared in the past. What do you think?
