Re: Question about Karin's personality and a little about Suigetsu
It was infatuation and when she realized how big of a douche he was, she knew he wasn't worth it. She DID NOT tag along because he was strong and almighty, she did it because she liked him. She saved his ass numerous times from Deidera, KB, Raikage, Danzo. Sasuke is the one who recruited her because he wanted to use her. She was just a tool to him but Karin viewed Sasuke, Suigetsu and Jugo as comrades and friends. Suigetsu and Jugo viewed each other the same way.
Naruto and Sakura is more in love with him. Yes, Naruto too. With Karin, it was infatuation which is different from love.
If they just tagged along for power then Suigetsu wouldn't have risked his life for Sasuke, Jugo and Karin when fighting 8-tails.
Jugo looked up to Sasuke as he did to Kimimaro. He would not have healed him.
Karin liked Sasuke. She risked her life by healing him more than a few times.
Sasuke used all 3 of them.
