But that's the question.. I hate to, but just like in Into Darkness - Kirk doesn't give a damn about it when a whole budding civilization is threatened, and even though he's baby Kirk from alternate timeline he'd still have done it in TOS without batting an eye.

It's something you have to interpret for yourself - Most people would say break it for the good of the people but as people we don't know what is good for the galaxy or beyond.. eh who knows
