The raptors in the first were explicitly insane, which is made more clear in the original book where their leader kills every new raptor they try to put into her pen and they throw themselves against the electric fence over and over again on the off chance that, this time, it won't shock them.The tribe in three was also perfectly reasonable once communication was established.

I wouldn't say that they were insane. The Big One certainly was bloodthirsty, as were the raptors in the second film. The raptors in the third film are considered a separate subspecies, based on biology and behavior. The [url=www.jplegacy.org/jpencyclopedia/?p=101]JPLegacy Encyclopedia[/url] dubs the two types as "Nublarensis" (JP and TLW) and "Sornaensis" (JP3)
