Orochimaru's parents! Why not revived?

[Hatsumomo]

Why Orochimaru never revived them with the Edo Tensei? It's not like he didn't miss them, he went visit their grave with the Third and Jiraiya also said that Orochimaru mourned them and even told to Jiraiya he can't understand him because he never lost someone important... than why?

 

[-Raviel-]

Because they'll ground him for all the people that he's killed :|

 

[Totsuka gg Amaterasu gg]

because they're irrelevant fodders

 

[Dr Strangelove]

Maybe he doesn't want them to see what he has become

 

[Child Of The Great Empire]

Maybe he thinks they would be ashamed of him?

 

[darkprince]

Because when the power blinded him and he forgot why he gained the power for.

 

[DocThao]

maybe he did revive them and they told him to attack Konoha or maybe they explained how Konoha was at fault for his death and that's why he wanted to get revenge against Konoha

or maybe he simply stopped caring as he got older

 

[Momochifanboy]

Or he maybe killed them.
