Karin didn’t let Sakura have Sasuke. He was never hers to begin with. Sasusaku liked each other way before he left the village. There was no place for Karin between them. Heck, even Naruto couldn’t get between them, not like he wanted to but he saw something in their eyes back at the hospital when Sakura hugged Sasuke.
If Sasuke had been single and Karin was like “Oh I don’t think I can make him happy so I’ll let him fall in love with another girl who can truly bring him happiness,” then it’s a different story. But Sasuke was already taken and married to Sakura when she decided to back down. Hence why she mentions that as long as he’s happy, she’s okay. And who does she see him happy with? Sakura. So how does she give him up so selflessly if he was already married to another woman?
You can’t give someone up who isn’t/wasn’t yours in the first place.
She had no choice. She either had to let it go or continue thirsting for him in her 30s and that would have been terrible.
The problem is that people put Karin on a pedestal and are obsessed with this fanon image of her who never existed. Karin the feminist, selfless, amazing goddess. And most of the time, they have an agenda for doing so because it’s always used against Sakura. Love Karin for who she is, not who you want her to be.
It’s good that she finally let go and found another way to be there for SS; another form of connection she has with them. She helped Sakura deliver her baby and they’re probably on good terms, but she’s not the selfless queen who gave Sasuke to Sakura. Sasuke was always Sakura’s love and vice versa. Way before Karin came into the picture. SasuSaku owe her no apology or explanation for falling in love, getting married and starting a family. What kind of logic is that? The only ones who want an explanation is them. Canon Karin doesn’t care, she’s happy and content with the way things are. I’m sure fanon Karin must be hella hurt and bitter, poor thing.
I am laughing so hard at marina btw. LMAO!
