This leads me to believe, that while F_Hiro may have believed that killing the exploding Sylar(in F_Hiro's Time-line) may prevent the catastrophe he had witnessed himself. I don't believe he truly knew the inadvertent consequences of making the most powerful person(Peter) nearly invincible, would have.
Now, Linderman, among others believed the bomb was not only necessary, but pointless and impossible to avoid. The reasons for their faith in this catastrophe is what struck me first. When Nathan and Linderman were talking about the bomb going off, Linderman mentioned .07% world population as an acceptable loss by anyones account. What if he meant when you can save millions of lives by allowing/ensuring the explosion.
Linderman was of course ridiculed by Nathan for his resolve, calling him a "lousy humanitarian". I've never believed this to be true, whether it was the graphic novels, a few lines here and there throughout the show, I still never really viewed Linderman as a bad guy.
I just felt he knew a bit more about the future then what we saw in Isaac's paintings, and the other artists' paintings he had in his "Road map to a brighter future". During this same scene, Nathan mentions that he knows a guy in a painting Linderman has, the painting is of Hiro saving the girl from being hit by a bus. Linderman then tells Nathan "If you see him, tell him I want my sword back". While he may have been saying he wants the sword, he bought, back, I believe that Linderman is none-other-than Takezo Kensei.
I also believe he intended on Peter dying during the explosion, he may have wanted this as to prevent anyone taking leadership from him... or perhaps, he was avoiding even more deaths. Peter has too much potential for power, it wouldn't take anyone long to realize this.
Finally, I think Kaito's [physical] response/reaction to "the hooded man" could be hinting at the fact that Kaito didn't defend himself with his [multiple] powers from this person, because this person could use all the same abilities against him. If Kaito is truly as powerful as I've seen mentioned, there's few that could match up with him, and this would include Sylar. So far the only people we've seen that have the potential to negate anyones power, has been the Haitian and Peter. The Haitian was sick during the death of Kaito, so this leaves me to believe that whether or not Peter is killing the first generation heroes, he may be the only one we've seen capable of doing so.
Guess we'll have to wait and see
