Let's look deeper at the real question they faced: How much risk (of life and limb) is it worth to save a chimpanzee's life?
Obviously the answers aren't 0 or 100%. If it was 0%, then we wouldn't have zoos, zookeepers, pets of many species, farms, etc. 100% means it's worth trading certain death for a human to save a chimpanzee - arguable philosophically, but for the sake of this discussion, I'll rule it out.
The answer is in-between. Everyone takes risks around dogs, horses, cattle - small children play with most of them. Zookeepers take much greater risks, it seems, around wild animals. So do hunters, tourists, etc.
How much risk do we tolerate? Do zookeepers take 1/1000 risk of death over their careers?
