Yes, sorry. I intended moderate in the style of his uncle Louis XVIII (who was pretty liberal for being a Bourbon). Really was the Duke of Angouleme the more moderate of the two brothers? I ever heard and think of the Duke of Berry as the more moderate of his family (maybe the trouble with Charles X's sons is who their wives are better know then them).
However, whatever was his ideas, Berry was popular and foremost a grown man, intelligent, perfectly capable of understanding that times had changed and act accordingly (and educate well his son, after all Caroline was horrified by the kind of education given to her son by her father-in-law and sister-in-law but she can make nothing for changed it).
Well, Berry was much more loved by the people, but he has been described by a lot of biographers as being as reactionary by his father. I think his open and frank manners would save him though, as he'd not make the same blunders as his father: he had been born in a different time and wouldn't make the same mistakes Charles X made, such as awful anti-sacrilege act (which essentially made it a crime punishable by death to steal
sacred hosts).
Angoulême was pretty conservative too, but he was actually pretty moderate. The only issues with Angoulême was that he was very timid and shy. He was essentially dominated by the Duchesse d'Angoulême, who as I said, was the most conservative member of the family aside from Charles X. As such, any potential ideas were pretty much nipped in the bud. He wavered on abdicating for the twenty minutes he was king in 1830, for instance, because of his wife berating him and telling him not to abdicate.
Louis XVIII himself wasn't exactly liberal, but merely pragmatic. I would say the Bourbons were intensely conservative to their undoing; there are just certain kings of that dynasty that made those blunders and paid dearly for them (ie. Charles X in France, Ferdinand VII in Spain, the various Kings of the Two Sicilies, ect.) which sort of tarnishes the family as a whole. We can't really forget some of the
good Bourbon monarchs, such as Henri IV; he reunited France, ended the civil wars, and even extended religious tolerance to the Huguenots, although this was quickly undone in the next reign. Louis XVI was also far from a tyrant, although he merely on the losing side of history.
