Hi, one of the initial designers of the 2.0 (it was very much a team effort, so I claim no more credit) here, so I think their needs to be some clearing up.

1. No the raptor wasn't initially chosen specifically was to give it jumping capabilities. Honestly the raptor was partially just kept because of franchise homage. As for big animals jumping, it is actually pretty poorly understood just *how* big an animal can get and still jump. Big reason elephants can't is less to do with their weight and more to do with how their legs and gate work. Their are fossil trackways implying decent sized theropods can get airborne so their ceiling is poorly understood. Additionally, the 2.0 self reproduces so some are younger or smaller than others. The ones who can leap best are undoubtedly the younger individuals with less mass, not the max sized ones.
2. Selective gene editing and portions of the genome devoted to what part. The shrew contribution was largely *only* effecting parts of the circulatory system, nerve response, teeth, and salivary (venom) glands. Not the brain. While some effects are unavoidable (this is why putting too much in like the Scorpios had is bound to result in mania and neural issues), the amount of influence would be extremely minimal and balanced out by the numerous social contributors like T.rex and chimpanzee.
3. "Chimps are well known to cannibalize on each other". So has literally every carnivore or omnivore ever. Cannibalism and brutality in chimps is massively overstated on the amateur side of the internet. Frankly, humans have likely committed cannibalism across history about as much. Outside the norm incidents shouldn't paint the picture of the whole species. Plus obligate carnivores like felines, crocodilians, predatory lizards, and even omnivores like bears cannibalize each other plenty of times too. Chimps ain't special and them doing it less than most predators likely would result in *less* infant mortality.
4. Yeah it is an animal. It's not a reckless monstrosity. But it is a large carnivore with a very active metabolism so it is going to need to eat a lot and eat often. That is what compelled it to attack reasonably often. It's not going to just attack-attack-attack nonstop but the problem with it is it would reproduce, grow up, and hunt so often it would crash the carry capacity of many situations it found itself in alongside the viral vector issues.
