A dick is someone who doesn't care about anyone, precisely what you characterized Cloud when you started the debate again.
You made a broad claim:
"You argue that Cloud is a dick to everyone else except Aerith..."
Do I argue that Cloud didn't seem to care for anyone prior to the introduction of Aerith?
Yes. Do I argue that Cloud is always a dick throughout the entire compilation?
No. Notice how I say things like,
"During the beginning of the game..."
Anyway -- Cloud *IS* a dick in the beginning of the game.
His dick behavior really shines during his exchanges with Barret:
Cloud: I don't care what your names are. Once this job's over...I'm outta here.
Barret: Little by little the reactors'll drain out all the life. And that'll be that.
Cloud: It's not my problem.
Barret: The planet's dyin', Cloud!
Cloud: The only thing I care about is finishin' this job before security and the Roboguards come.
Cloud: Shut up! I don't care about either Shinra or SOLDIER! But don't get me wrong! I don't care about AVALANCHE or the Planet for that matter!
All of these exchanges refer to Cloud's lack of care for other people besides himself. Then, when Cloud expresses his desire to save Aerith, Barret says,
"So there are times when even you fight for other people. I am impressed."
Barret's observation is obviously in reference to the exchanges Cloud and him had during the beginning of the game. If you can't see the significance of this observation, I don't know what to tell you :/ To me, it is clear that SE set Cloud up to be someone that didn't seem to care for others. But then, with the introduction of Aerith, that started to change. SE helped show us this change through the exchanges Cloud had with Barret.
Not even one about caring about her. Cloud's still a dick because he doesn't care.
I did say that one of the reasons may have been that she was a childhood friend of his.
You just said the party follows Cloud because the game requires it, implying that it's not because they sincerely wants to rescue Aerith. And they way you just characterized Cloud as a dick, I wonder why these amazing people would follow someone like him.
Yes. That is true. I don't think that any of these characters would have rescued Aerith if Cloud had not decided to do so. That's what typically happens when one person is the designated leader of the group.
But as I've already stated -- good for Tifa! She's a caring person and wanted to rescue Aerith. But the point I'm making is that Cloud began to *CHANGE* because of Aerith, which tells us that Aerith is someone very special to Cloud. On the contrary, Tifa did not show any *change* by agreeing to rescue Aerith because she's always been a caring person. However, the Cloud we were introduced to at the beginning of the game would NOT have rescued Aerith. Only until getting to know Aerith, did the Cloud we were introduced to at the beginning of the game start to disappear.
Given your characterization of Cloud, I feel sorry for her.
