@Linkat,
You have it backwards, Linkat. I am not "attributing human traits to animal".
I am attributing animal traits to humans.
When I feel threatened, my brain floods with neurochemicals designed to get me ready for a flight or fight response. My cognitive function shuts down, my emotions and anger rise (this allows me to make quick decisions in a high risk situation which has had evolutionary advantage). This is a well known and well studied reaction that is not uniquely human although many decent and educated human beings experience rage. The brain chemstry is the same in humans as it is in other high order animals.
Humans are animals and we are subject to the same evolutionary instincts as any other animals. Many animals show agression, sacrifice to protect their young, have a sex drive, I don't see how these traits common to many animals would be any different. The "joy of the hunt" has to do with adrenaline and brain chemicals, the brain circuits to enjoy killing developed in cats, and whales and wolves is innate. Why wouldn't it be the same in humans.
It is well know that decent humans, when faced with danger, can revert to animal behavior that is often quite brutal. The instinct to expand our territory and defend our group and eliminate threats that champanzees and wolves and bears show are also present in humans.
Humans have this additional capacity to think symbolically and consider the meaning of their actions. Sometimes humans use this added capacity.
That doesn't change the fact that humans are primates with the same basic instincts that we evolved along with our primate cousins.
