I disagree. FFV showed X-Death. FFIV had Golbez. FFVI the bad guys killed lot's throughout the entire game. FFX they kill all the time as well
I don't know that part when is it?

Obviously you haven't (SPOILER)gotten to the end of the game, cause Garland IS the final boss. He transforms himself into Chaos at the end.
No I only bought the game a week ago ut I knew that anyway and this was BEFORE the (SPOILER)time-loop
