Yeah chimps can sometimes snap, but their DNA is something like 98% similar to humans, so the similarities (physically and mentally) are crazy. Still, there's way more humans that are fucked up than chimps.
Normally if an animal attacks or does something vicious, it's because they feel threatened or are defending their territory. It's rare that they do something shitty for no reason at all. They go off instinct.
And why do you feel that if it's between a human and animal life the human should always be chosen over the animal? I can't understand why people feel that way. Animals have feelings and emotions just like humans do. Animals feel pain and happiness just like humans do. Animals have family, kids, and friends like humans do.
The difference? Animals (at least pets like cats, dogs, etc.) will show you unconditional love if you treat them right. Many people on the other hand will stab you in the back the first chance they get no matter how good you have been to them. Even family and close friends will do it to you.
Just because animal's brain capacity isn't as developed as humans doesn't mean their life is any less significant. If your argument is based on intelligence/brain capacity, then does that also mean if it's between a smart person and a dumbass that the idiot person should be killed so the smart one can live?
If so, this world is full of idiots and our population is already too damn big...maybe we should round them all up and exterminate them all? Or maybe if someone commits murder, the punishment should be based on how smart the victim was?
See, where do you draw the line?
