That's a perfect analogy. It's not like humans haven't caused the wilful extinction of other animals and humans genocidally attack insects and arachnids every day. We try to kill other mammals that share most of our DNA for food and clothing or animals like rabbits with myxomatosis and calicivirus. I think Sunstreaker has every right to want the human race wiped out. And as he's a giant robot, we should be less than mosquitos to him.
