Fighting would inevitably cause collateral damage, injury or even death but if that was the objective then those things just came as a consequence. A consequence that Sephiroth knew well. It wasn't a case of accepting that lives would be lost, that livelihoods would be destroyed...Sephiroth had already accepted that- he now had to move on from that and think objectively.

It was unacceptable to allow himself to become so connected emotionally, yet at the same time those connections he had with others in the City was what the military effort would come to rely upon.

"As much as it's important that Aqures remains standing, going in with an impossible dream simply isn't going to cut it - we'll be much too stretched as it is. I believe that the local security forces are best positioned to plan with regards to defensive stratagem but much like the military force there is limitation there."

Cool and callous, to the last.
