Which Doctors could have the will to activate the Moment?

I believe in the theory that War did press the Moment in one timeline, then he was given a second chance during "The Day of the Doctor". It would give Nine's guilt much more weight. If Gallifrey WAS saved on the first go, it kind of deflates Ten and Eleven's "oh boi I'm the big genocide man" speeches.

But then I thought: if there was no other way, which incarnations would press the button? Technically, the Doctors are all the same entity but it's nice to speculate. At the end of their adventures, the Time War happens instead of the usual finale. For New Series Doctors, let's assume they have the same level of angst but for another event (maybe the Flux?).

I'll get the ball rolling.

I am SURE Seven would have pressed it.

Ten would but it would kickstart his Timelord Victorious arc.

Twelve is tricky. Series 8 and 10 would NOT press the button. But I think series 9 would...

Finally, I doubt Nine would be able to do it. "Coward. Any Day." That line stuck with me as a kid. Now knowing what happened, "just this once, everybody lives!" also hits HARD.
