Gotta love the left-handed compliments Crystal dishes out.
He's not poking fun at Kuja when he brings up his "angry tantrums". It's kinda like how I'm not poking fun at Tidus when I say he "whines a lot."
Tantrum and whine are typically negative descriptions of anything. If you weren't poking fun or being insulting as you almost always are, you would have said he perhaps went into a fit of rage at imminent death or he was extremely angered by te fact Zorn and Thorn weren't getting the eidolons from Eiko.
But you chose angry tantrum, something you'd choose to describe a little child thrwoing around toys because he didn't get his way.
So, please, don't try to hide your fanboyism.\
At least The Crystal is honest here on what he thinks of Kuja
