Wow.Major spoilers concering Aeris dude.

Alright,well.I agree with you on most points.Aeris died to fuel the hate for Sephiroth.I also believe she died to make you more connected to Cloud,and the other characters.You could feel what they were feeling.I know the first time I played the game,i went thought disks 2 and 3 feeling like somone was missing(not just from the part,or from the characters,but somone in my heart,you know).I believe that that may have also been a resons they chose Aeris to die and not Tifa.Tifa you saw as a lover for cloud,and a total slut(im sure many if not every one of us reflected that her clothes were to little and when she talks to johnny or went into dons place,we got some ideas).Tifa you saw as a shallow person,who hated Aeris.Aeris you saw as a king,gental soul.( the working in a bar and having flowers grwing in a CHURCH might have made you feel one way or the other).This ment that if you killed tifa,some people would feel down while others would be pleased.MORe people would cry at the death of the flowergirl.

As far as your Cait Sith and Aeris comparison goes,I agree with you totaly.

Now,your last topic.Why did Cloud break from Jenova/Sephiroths grasp of power?You say love for Aeris,Cloud was stronger then Sephiroth all along,or Jenova didnt have good controll in this holy place...You know,I believe it was because of Zack.Cloud was Zacks best friend,most likely HAD seen Aeris before,with Zack,and most likely had feelings for her like his friend did.Now,dont think my idea totaly off just yet.Cloud forogt himself when he was Zack,and forgot bits of Zack aswell,so when he had to answer some of the questions about himself,he was actually answering things Zack may have said.Remmeber,sometimes he couldnt remember.I believe,because cloud WAS Zack when Aeris died,he didnt kill her because of Zacks love for her,and Jenova/Sephiroth didnt have controll over Zack because Zack is actually dead.
