Why did Tsunade drug jiraiya?

[Tyrannus]

If she was going to try and kill orochimaru anyway

 

[Oblivionx]

she wasn't. she changed her mind later on.

 

[Horus]

He didn't know she was planning on killing him. He thought she was gonna help him so to avoid having him in the mix to create difficulty, she just took him out of the equation.

 

[Mori Jin]

Plot otherwise Sage Mode Jiraiya would have destroyed orochimaru.

 

[NarutoX28]

She contemplated on using them as sacrificial pawns for Edo Tensei yet decided against it in the end.

 

[Chihaya]

pls dont question the actions of us women, it is very unwise and rood. thxs!! ;P

 

[Livenojutsu]

Tsunade at the beginning wanted to resurrect Dan and Nawaki but later she changed her mind

 

[LuckyMan]

She didn't want Jiraiya to kill her.

 

[Amenotejikara]

so she can revive jiraiya's cockblock and her fodder brother.
