Intelligence is arguably humanity's strongest survival trait or at least one of them (our adaptability and curiosity are the other two major traits I can think of that would vie for pole position). However, in our pursuit of our own survival we have caused pain, death and extinction to other species.

Is it evil to use an inherent genetic characteristic to the detriment of other species to ensure our continued existence? Without our more advanced intelligence we would still kill and displace other species just as everything else in the food chain does. Is it that some of the uses we put our intelligence to that are evil?

Is intelligence unnatural, a mistake? Does anyone think that we should not have evolved as far intellectually as we have? Is it a disadvantage as well as an benefit? Thinking about the things we do can sometimes make us alter our present course; should we ignore analysis and simply outrun as many species as we can in the race for survival? Is thinking slowing down our progress as a species?
