well, it's fairly obvious you don't -- judging from the timeline mistake you made in your first post. also, Kirk wasn't the one who committed the genocide. the black hole was a tunnel. if he let the Narada go through it, it had a chance of coming out on the other side in possible other timelines, giving Nero a chance to create further mayhem with other timelines. the best way was to destroy Nero. Kirk didn't WANT to do it, but did it when Nero pretty much asked for it. I think you need to question your choice of words before you post them.
