Because Orochimaru would come find her.
Considering how Sarada was less than 1 meter from him and he didn´t give two fcks in regards to her, I doubt so.
You´re grasping at straws here.
You really think he's gonna let Karin leave without a word?
If Sasucakes said so, then she leaves. Orochimaru can´t do anything with Sasuke involved. So again: the only thing she needed to do was to say "Sasucakes, I don´t think oro´s lab is a suitable place to raise the baby. Can we go to another place"
SO hard to do!! /sarcasm
Maybe Karin wanted Sarada to have a normal happy life. A lot of parents do that in life. They will their child to another family, because they cannot protect them and/or they believe they deserve better.
Hohoho, this is a rich one.
Unless said parents are in the worst situation posible (A.K.A. completely alone -Karin wasn´t, Sasucakes is powerful and is alive-, absolutely broke -cough cough, Uchiha money cough-, and so weak they can´t protect even themselves -once again hellooo... Sasucakes is basically one of two most powerful beings alive in the NV, only Naruto can kick his @ss-) this is only the convenient excuse irresponsible adults/teenagers use to avoid taking care of their abandoned children.
Taking care of their kids by themselves, providing all those children with those things they need (love, education, food, playtime, etc) is the most important thing -heck, the privilege- any true parent won´t sacrifice unless absolutely necessary.
Any "parent" that is NOT in this situation simply is one that renounced said privilege before trying it... A.K.A. a deadbeat irresponsible one.
Maybe she didn't want her to become an experiment like she was.
Since when is Karin a lab tube baby? She surely had parents; after all we DO know she was affiliated with Grass in the chunin exams. She wasn´t an Oro follower since forever.
And like for the third time: who says Orochi would do (lol, more likely could do) anything to her or Sarada had she been under Sasu & Naru protection?
Maybe she wanted the best for Sarada. And with Sarada in Konoha, she is perfectly safe, especially with Sakura, Tsunade, Naruto, and the others.
Is Karin banished for life from Konoha? Is she under some kind of death penalty that not even Naruto´s influence as the Hokage can´t make invalid?
Once again... nothing prevented her from becoming a ninja from the leaf... heck I bet the Coucil would have jumped at the oportunity of getting such powerful "blood" for Konoha.
To end this rant... consider what you wrote back there: are you implying Sakura et al would have been better for Sarada than Karin no matter what? Are you really trying to justify her by bashing her in the process?
/facepalm
Uhh Karin taking control of her life and becoming a responsible enough adult to afront parentage as she should have? (and by this way preventing the suffering ultimately Sarada got with this mess)
Read my second comment
We did, the only thing I concluded of it was: "Karin was apparently abandoned by Sasuke -if not the Orochi menace frankly is lolworthy considering Sasucakes´s power- and of course the best course of action was to drop the baby in Konoha. Not even trying to raise her was the most responsible decision she made, we must applaud her for her ubber responsible decission making U_U"
For the record: you basically implied she would have been a terrible mother no matter what so of course abandoning the baby was the best thing ever... /facepalm
My opinion: up until now, she just acted like the average selfish woman that gets an unwanted pregnancy and grasp at straws to justify why she rather continue with her life plans instead of owning to her duty as a mother.
