You're kidding, right? You do know we slaughter dolphins as by-catch with many fish species for food, and apes have in fact been killed because of the expansion of human habitat.
What are "principles of intelligence"? And whatever they may be have they prevented humans from slaughtering other humans? Now try to imagine an intelligence as far advanced from us as we are from bugs. I actually try not to harm bugs if I can avoid it, I'll carry them outside if I find a few in my house, but if there is a horde of ants I'm breaking out the ant traps, and I'm sure I killed thousands when I built my garage a few years ago. We won't even get into the topic of eating meat...
You raise some good points. Indeed, there are atrocities committed against apes/dolphins. However, we recognize these as inhumane acts and condemn them. We are making efforts to help and preserve these species, we have many people and organizations devoting their life to these efforts.
My point is, that even if the difference in intelligence between the ASI and us is more akin to us vs bugs, the ASI will still see and treat humanity at least as well or better than we treat primates, not as we treat bugs, simply because they will recognize us as the closest to them.
Our best chance of creating general AI is to mimic how our own brain works as closely as possible. Also, there is a good chance we will have human-AI hybrids - brain-computer interfacing - (cyborgs if you wish to use scifi term), before we have human level AI purely in silicon. Our value system would be naturally "inherited" by the AI this way.
