There is a difference between instinctual morals and reflective morals. Chimps do have instinctual morals -- they react reflexively in moral ways. They are on their way to evolving a more complete morality. But it's not there yet because they don't yet REFLECT on moral issues the way humans do. Let me give you examples of the difference.
Your son is a heroine addict. He can't hold down a job. If left to himself, he ends up on the streets, without food, stealing for that next fix. You are terrified he is going to die from any of a number of different reasons. So you take him in even though he uses you, mooches off of you, steals from you, and uses the money to support his habit. He doesn't even help clean the house, but is a slob. But your compassion for him and your fear for him have you acting reflexively, instinctively out of empathy.
Reflective morality would have you look at the same situation long term, and see that you are only enabling your son, worsening the problem. You see that if you truly love him, you will do what it takes to make the reality of his abuse hit home, and you will not feed his dysfunction, will not contribute to it. As painful as it might be, you will not give in to your natural senses of fear and empathy, and you kick him out. You set him up in a furnished apartment with a butt load of food, and give him leads for rehab. Then you cut the chord, no matter what his pleas. This is reflective morality.
Sometimes reflective morality lines up with instinctual morality. Sometimes it doesn't. But the point is, you think it through. You may decide that what you did was wrong, and experience guilt. You may resolve to do differently in the future.
