Why does everybody hate Cait Sith?

[Carl the Llama]

for a start Cait Sith would of turned the temple into the black materia even had we not approved coupled with the fact that he said that he kidnaped marlene and said that he would come along even if they didnt want him to...

I doubt he actually kidnapped her in the manner that he implied. I don't see Reeve as the type who would have kicked down the door of Elmyra's house with a swarm of gun-toting soldiers behind him to capture a little girl. He probably very simply just told Elmyra that she and Marlene would be safer in Kalm and offered them an escort to get there.

If an old man comes and says come into my car i have candy to a child in a playground or something like that it doesnt require the force your talking about, and even if he didnt do that, who said it was him who kidnaped her in the first place, kidnapping is the work of Turk's not some shinra manager.

I didn't get the impression that Marlene was terrified when Cait Sith let her voice come through the radio he held in the Gold Saucer. She seemed more surprised than anything to be hearing their voices, especially Aerith's.

the fact of the matter was not weather she was treated well, in fact if she wasnt treated with utmost care and respect im sure they would do anything to get her back... its a fact that even if your kept in a palace against your own will it also is a prison no matter how well they are treated and if they didnt let Cait Sith come along they would have taken action against the group by do somthing to Marlene

i do like him for the fact that he would do anything for his people... had (SPOILER)Reeve joined the party himself instead of haveing some big stuffed mog in your party the fact of the matter no matter how many times he could of died he would still have a replacement anyway, if (SPOILER)Reeve would have come out to the front line himself he would have earned my respect but he never did so i dont like him.

They never really went back toward Midgar until Disc 2, at which time (SPOILER)Reeve was going to go with them himself, but (SPOILER)the Shin-Ra soldiers had arrested him already and were still after him, so he had been taken in by some of Midgar's citizens:

(SPOILER)::Cait Sith comes back online::

Barret
"Well lookey-here. The Shinra manager's come back."

::Cait Sith stands up and goes over to the group and bows::

Cait Sith
"Uh, excuse me but..."
"I wanted to come with the main group, but I couldn't get
away......"
"So some people in Midgar took me in."

::He straightens back up::

Cait Sith
"I know I have a stuffed animal body, but I'll work really hard!"

So it's not really like he didn't want to. Besides, (SPOILER)being in Midgar allowed him to make sure everyone got in the Slums when Meteor started coming down, so it was probably best that he stayed there.

one thing i dont understand is when at the end of disk 2 he goes to midgar to check on his people when he should of already been there?

What scene are you referring to? They go to Midgar the first time because Diamond WEAPON was flying toward it and they were trying to protect it. They go back because Hojo went insane and was going to fire upon the Northern Crater with the Sister Ray a second time, putting Midgar in danger.

im refering to the sceen where cloud says to everyone on the highwind
(SPOILER)Cait Sith: Shinra's...... finished.

Cloud: Meteor's gonna fall in about......

Red XIII: Seven more days. That's what Grandfather said.

Cloud: Red XIII...... You want to see everyone in Cosmo Canyon again?

Red XIII: .........yes.

Cloud: (to Barret) You want to see Marlene, right?

Barret: Don't ask me that.

Cloud: We'll beat Sephiroth... Then, if we don't release the power of
Holy in seven days...... There won't be a planet left to protect. If we
can't beat Sephiroth... It's as good as death for us. We'll just go a
few days sooner than the rest who'll die from Meteor.

Barret: Don't be thinkin' you're gonna lose before you even fight!

Cloud: No! What I meant was... What are we all fighting for? I want us
all to understand that. Save the planet... for the future of the
planet... Sure, that's all fine. But really, is that really how it is?
For me, this is a personal feud. I want to beat Sephiroth. And settle
my past. Saving the planet just happens to be part of that. I've been
thinking. I think we all are fighting for ourselves. For ourselves...
and that someone... something... what ever it is, that's important to
us. That's what we're fighting for. That's why we keep up this battle
for the planet.

Barret: You're right... It sounds cool sayin' it's to save the planet.
But I was the one who blew up that Mako Reactor...... Lookin' back on
it now, I can see that wasn't the right way to do things. I made a lot
of friends and innocent bystanders suffer... ...At first, it was
revenge against Shinra. For attackin' my town. But now...... Yeah. I'm
fightin' for Marlene. For Marlene... For Marlene's future... Yeah... I
guess I want to save the planet for Marlene's sake...

Cloud: Go and see her. Make sure you're right, and come back. All of
you. Get off the ship and find out your reasons for yourselves. I want
you to make sure. Then I want you to come back.

Cid: Maybe ain't none of us'll come back. Meteor's gonna kill us
anyway. Let's just forget any useless struggling!

Cloud: I know why I'm fighting. I'm fighting to save the planet, and
that's that. But besides that, There's something personal too... A very
personal memory that I have. What about you all? I want all of you to
find that something within yourselves. If you don't find it, then
that's okay too. You can't fight without a reason, right? So, I won't
hold it against you if you don't come back.

Everyone left, then with Cloud and Tifa solo...
