He didn't activate, kabutoro did. Pein felt the pressure as amaterasu; it was going to be a genuine attack from kabuto's end.
-----------------
Is Kabuto really that well placed and able to focus on each individual and battle? I thought Edo Tensei was more like the person resurrected fights to their best ability in line with the objective set to them by the one controlling them. I can't see how Kabuto would know he jutsu's of all the people he has resurrected, let alone when to use them.
Also doesn't anyone else find it weird that a human eye can fit a crow and work?
That's magic, this is supposed to have some science behind it!
Yeah, but even so it should stand to some amount of scrutiny. It's kind of badly done.
"You are not free whose liberty is won by the rigour of other, more righteous souls. Your are merely protected. Your freedom is parasitic, you suck the honourable man dry and offer nothing in return. You who have enjoyed freedom, who have done nothing to earn it, your time has come. This time you will stand alone and fight for yourselves. Now you will pay for your freedom in the currency of honest toil and human blood."

Coherent stories and shōnen manga arent close friends I fear. Anyway I personally prefer that we dont get any explanation to these "miraculous" things. Hate it when writers just call their readers stupid to their faces with some new and unbelieveable explanations.
The path of excess leads to the tower of wisdom
can't imagine how powerful Naruto is if he's in Nine Tailed-Mode and Sage Mode at the same time.
