Those gorillas are struggling to feed their kids too, while dodging bullets and snares. Most often they are killed so that their hands can be sold as “souvenirs”. They are often found with their hands cut off. Humans do this, and they’ve been doing it for a long time, to each other and to the gorillas and other primates and other very sentient family-oriented creatures like elephants. Maybe you should look into the eyes of a young, still-nursing gorilla, while it watches a gang of human thugs kill its mother, cut off her hands, and carry them off, leaving her mutilated body behind.
On and on we can go, arguing that every single plant and animal on earth would be better off if humans weren't around. And after humans, the next predator in line, and so on and so forth. eventually the entire earth would be devoid of all life except one single plant.
We are part of the food chain, get used to it.
