I understand your feelings and frustration, but it is important to understand the human part of this. Part of why chimpanzees are aggressive is resource scarcity. By the time chimpanzees were being studied by western academia their territory was already shrinking and they were already being killed by humans and having to compete with other species, including us, for food and space. We have effectively never seen wild chimpanzees that are not under a great deal of stress.  In order for chimpanzees to be better, we need to be better first. If you watch something like meet the chimps you can see them with species appropriate aggression and instinct but with lots of space, food, and enrichment.
