Possibly, yes. He's got _something_ invested in the venture XD (Well, Hojo's soul got eaten by Sephiroth - no, I am entirely not kidding (http://www.hojo.org/index.php?page=ultimania) - and I don't count Aeris because she may be dead, but she still comes back and screws around with everything _anyway_. And I bet Zack totally _does_ watch him in the shower. Perv.)
It's like the red-shirts in Star Trek! They exist only to be killed off.
I'm inclined to agree XD
