[Cloud purses his lips, almost looking offended at the comment. He looks about to shout but then he stops, and takes a breath.]

He...was my childhood hero. I grew up idolizing him. I wanted to grow up and join the army and be a hero like the 'Great Sephiroth'.

[Anger welled up within him.]

He destroyed my hometown and all the people living there. Tifa was the only other survivor and just barely. My best friend got me out but...he died protecting me...and then he came back from the dead...twice...to try to destroy our whole world.

So no...there's nothing he can do.
