unfortunately there's a bunch of simping by karin here, in the next chapters will vote for karin plus the whole village to be harem...
I vote A help Karin but remember we will only be able to actually have Karin in two situations, situation 1 Shinji defects from the leaf to have her or situation 2 Shinji rises extremely high in rank to the level of Danzo or Hiruzen to accept her into the village because the last pure blood Uzumaki asking to join your village is extremely sus they would assume she’s a spy and look into her background thoroughly then have the yamanaka’s due an in-depth scan of her mind and even then she would be monitored constantly by anbu because she may be a sleeper agent so she would probably end up not being allowed to pass the rank of jonin. Also hiruzen is dying soon meaning easy puckings for Danzo to use Kotoamatsukami and make her join root. so that means we need to consider going rogue or becoming hokage to have Karin and I’m leaning towards Hokage so in my opinion Shinji’s long term goal should be to become the hokage.
A pretty self explanatory, too drained mentally to comment more detailed reasons so I will just post the short versions 1. It's Karin 2. Potential ally 3. Shinji can look into it to research how Karin's blood work and might in the future recruit her as his assistant in lab ( post Shinobi war, probably) 4. Have her go under Tsunade to protect her from Danzo since he wouldn't move directly unless it's very important and Karin isn't really "worth" it, except the uzumaki bloodline thing 5. free emergency revive card
