In the wild, there were times he’d had to kill another animal either for his survival or sustenance, but it was different now. He wanted to kill just for the act of extinguishing another’s life. Not for joy or food or to make sure he stayed alive, but just because anything and everything in his path needed to die. It was as uncomplicated as that. The gorilla chased the humans through the torture labs, wanting to separate limb from body, using his large canine teeth to rend body parts. He didn’t know the word, but “revenge” might have been appropriate. He’d been taken by force from his home and shoved into small cages, most not large enough to even allow him the ability to stand, much less turn around. They’d injected him with all manner of substances. Some making him so sick he wished he would die. Other times, they’d operated on him, cutting him open while he was awake. The pain had been so severe he did not think there could be anything worse. Then they’d injected him with sample number forty-four, and everything he thought he knew about the world had changed.
