- I do not agree that Sakura will feel like joining Sasuke nor will he invite her.
1) Sasuke gathered people who he deems useful and in line with his agenda which Sakura is not
- Juugo has brute strength and can use animals to scout locations and stays with Sasuke because he believes Kimimaru spirit lives on in Sasuke to some extent.
- Karin has superb chakra sensing abilties and a healer and was lieutenant in Orochimaru's Sound village Experimental hideouts
- Suigetsu is a direct fighter type who doesn't hesitate to kill as he is described by Kisame as the second coming of Zabuza who loops off heads for fun.
2) Sasuke is not the type to open up and explain everything in his heart just because someone asks.
3) Even if he did is Sakura going to say....
lol gimme a f*ckin break!Sakura: Oh no well the elders & Danzou tried to kill you I cant accept that.....
Sasuke: Its true now I need the power of Tailed beast to kill everyone in the village plus the Elders including your parents so I can get my revenge and rebuild the clan.
Sakura: That would mean killing Naruto to get his tailed beast hmmm.......Sounds reasonable lets do eeeeeeet!
Sasuke: Welcome to Team Hawk now we all move as one come Juugo, Karin, Suigetsu , Sakura-chan lets doeeeeeeeeeet!
Suigetsu: do eeeeeeeeeeet!
Juugo: do eeeeeeeeeet!
Karin: do eeeeeeeeet!
4) People seem to underestimate Sakura's resolve and her morales did you guys not see the Sasori fight.
She did not hesitate to jump in the way of a friggin poisoned Katana to protect Chiyo nor did she just give up even while stabbed and poison spreading through her body she refused to let go.
- Sakura will never join Sasuke regardless of the reason behind what hes doing because to her hes doing immoral thing which will threaten the lives of everyone in the village.
Do you really think Sakura would throw away her friends , parents, Master Tsuande and Naruto like trash just because Sasuke winks at her.
- More likely in fact when Sakura goes towards Sasuke Kabuto will spring up like a snake in the grass and do what ever she was planning to do probably poisoning him somehow.
Those stats have not been revealed altho I created a thread where I estimate them based on what we have seen of his fighting style.
