[Star Trek Into Darkness] Surely they were breaking the prime directive even if they weren't seen?

At the begin where spock uses that cold fusion device to cap the volcano it freezes in a very unnatural fashion.

Assuming they develop an understanding of geology before they achieve warp they will know something funny has gone on and a pre-warp civilization will know it has been interfered with. 

So why was spock so hard on Kirk when he was already breaking the PD anyway?

The reboot movies show time and again that Kirk makes awful decisions that only pay off due to unforeseen circumstances out of his control later on, and that Spock is the one that should be in command of the Enterprise.  He simply didn't care that they were breaking the Prime Directive, or that both he and his second-in-command were placed in direct danger for the sake of a thrill.  Seriously, what was with that bullshit where Kirk and Bones decided to engage the natives and steal the scroll they were worshipping?
