Why did Sasuke burn the blades with amaterasu?

[NoOneSpecial]

In Gaiden ch. 9, why did Sasuke burn the blades after he pulled them out from Sakura's arm? Kinda confused :dunno:

 

[Dantee]

So that shin could no longer control them.

 

[Esdez]

to eliminate the poison in the blades, which can cause paralysis

 

[Dantee]

Cause he is Sasuke and he is emo and likes burning things

Sasuke fans tend to have better reading comprehension. Take notes

He probably burn the mark seal that Shin put on it.
