The park didn't fail because of Nedry

"It was also stupid how Hammond was so anti killing an entity his lab could just make more of."

Because making them was insanely expensive. Also, in the book it talked about how the dinosaurs had an extremely high infant mortality rate and went into a lot of detail about the various problems they had, diseases and so on, and frankly there weren't very many of them (or at least didn't seem to be until it was discovered that they were breeding). So every lost dinosaur represented a large amount of money lost, and the very few dinosaurs that survived into adulthood were pretty much worth their weight in gold. Hammond being a capitalist, money was his primary concern. The movie kind of sanitizes him and makes him out to not care about money (because you totally become a billionaire by not caring about money), but book Hammond was pretty open about his greed. Every dead dinosaur was a lost investment.

"Why would they breed carnivores? I get the T-rex as the T-rex is more controllable compared to the human size raptor. Why breed raptors? Also, since they were aggressive, why were there a ton of them?"

Because it's an incomplete set without the carnivores. Hammond wanted to resurrect as many of the dinosaur species as he could. His vision wouldn't allow him to refuse to bring back a species on grounds of safety. Malcolm was trying to drill the concept of safety concerns into Hammond the whole book and Hammond just let it roll off him, not wanting to hear a word of it. And for the part of the scientists working for Hammond, they just wanted to achieve whatever they could and didn't think much about the dinosaurs themselves, another point Malcolm made a lot of in the book.

Also, from a marketing standpoint (which Hammond was all about in the book), how do you make a dinosaur park without carnivores, without the tyrannosaurus, the most famous dinosaur of them all?

As for the raptors, well, probably it's as you say, people at large didn't know about velociraptors, so it simply wouldn't be known how dangerous they were. Not to Hammond and his scientists anyway. Paleontologists like Dr. Grant would certainly know, but no paleontologist seems to have really been part of the project until Hammond brought Grant to inspect the island when the whole thing was already far along. In both the book and the movie it's clear that the security measures around velociraptors were increased over time as it was understood how dangerous they were as a result of the unpredictable, aggressive and intelligent behavior they demonstrated. When they were first born it wouldn't be so clear (in the book, the infant velociraptors were portrayed as docile and cute), but as they grew up, that was when it became apparent what a dangerous species they were.

While you're absolutely right, this is an artifact of the novel, where the park was in fact designed poorly because Hammond was greedy and cut corners. The design problems remained in the movie as part of the plot, but, with Hammond changed so much, they don't have a logical explanation anymore.

I mean, really, how many times will you look under Jabba's manboobs?
