He'd heard their footsteps
ps long before he'd laid eyes on them. Knowing fully what was coming up those stairs to meet him. Knowing, that soon blood would be spilled. Sephiroth didn't consider it a pity that these lives, who could have served somewhere else so much better, where soon to be, sacrificed. To be ended. But it was so...common for normal, petty humans to feel immense sorrow after having faced death. So why did ShinRa insist on sending these men --no, boys-- to come face him? To come die by his blade? Certainly the old fat man knew by now that it was him Sephiroth was after? Why, no matter what the old fool might have looked like, wasn't stupid.
He wasn't foolish enough to think he was going to survive this night, was he?
He didn't truly believe that these children, no matter what kind of weapon they were given, would stop him? Him, Sephiroth, once ShinRa's lapdog, now Chosen One of his Mother, Jenova.
ShinRa would die.
No one, not petty young men and women with guns, not the Turks, no one was going to seize Sephiroth of his price; to see that pig of a man dead.
This was also an introduction, a message to the world. He was back. Sephiroth was back and he was going to torment the world, to take his place as God, to rid the world of all and any who opposed him just as Mother had willed him to. Mother's word was law as was his, and these humans would soon know that.
And what better way to start than by removing the single most economically successful man on this planet?
Sephiroth couldn't think of any other answers, and when the silly ShinRa troopers came at him with their swords and their guns, he felt no pity. No remorse, not a hint of sadness; because this was justice, this was the way to a better world, one ruled by him and blessed by Mother. All of those still left alive at the end of his taking, would come to realize this and would come to worship him.
This much was certain.
This is what drove him.
And this is why, when the moment finally arrived, Sephiroth didn't hesitate, not at all, to bring down his blade on the fool sitting on top of his crumbling tower.
