That is true.
However, Jenova is the cause for Sephiroth, thus Jenova is the true enemy. Sephiroth is the main villain and the strongest in the game, but that doesn't automatically make him the true enemy.
Jenova cells gave him the power he has, and made him the way he is. So in my opinion i think Jenova is the dark one behind the scenes pulling the strings
