Pheobus was a married man (to "fleur de lise"), he was a pedophile (Esmeralda was 14), he was the man who sent her to her death (by hanging) to cover up his affair and his corruption (treason), he was violent (beat up peasants), and he allows Esmerlda to be sentenced to death for his attempted murder, despite knowing that Frollo was the one who tried to stab him, simply because Frollo was powerful (he was a coward), and Esmeralda was disposable, etc.
not what I would cal a valiant or noble man.
Frollo was better then him, he took care of his drunkard of a brother, saved Quasimodo from being tossed down a well (by unknown characters, not himself), took care of him as a (loving) father would, Frollo was a friend to the gypsies (he ran charity), he was a decent guy that went homicidally insane with lust, and he's the antagonist of the story.
Quasimodo was not as angelic as he was in this film, he was an attempted rapist (of Esmeralda), he was sent to kidnap her by Frollo, and did so (the kidnapping failed and it was the reason he was being whipped, the day of fools was another event entirely), also the festival of fools was a day when the man who could make the ugliest face would be pope for a day, and treated as a king (includes free food, beer, and wine, and watching Esmeralda dance for him, at which point he falls for her), not being punished, he also crawled into Esmeralda's grave.
the gypsies were evil, EVIL people, in the books, they are criminals, savages, and degenerates who took advantage of the french.
they threatened to kill a french musician they hired when they found he wasn't a gypsy, he got out of it by Esmeralda's offer to marry him, they get married at the start of the book, fucking lunatics, they also hated Esmeralda for stupid reasons, such as her being pretty (and NOT a gypsy by blood).
The french weren't as bad, but they still had their problems, for example, they thought Esmeralda was a witch who had sex with the goat she taught to dance (and count), they also thought the goat was the devil.
