Sasuke needs to say thanks to Orochimaru

[Hebi Sasuke]

Hashirama didn't have the Kyuubi.

 

[fayeon]

Sasuke only thanks sakura

 

[blazekev90]

He also trained himself in Shape-Nature Manipulation(Chidori)

Yeah...um no! He was taught this

 

[Kishi Uzumaki]

He should thank him for training him and curse mark but he wanted his body right so no need to thank him . he should thank itachi for giving him eternal mangekyo and kakashi for teaching chidori . they didn't wanted anything from sasuke like orichimaru .

 

[Avani]

Well Madara , Sasuke and Konoha all have something to thank Orochimaru for if you ask Oro.
