...animals would extinguish other animal species if they could. And yet again in fact they have.
I disagree - there where animals were "extinguished", it occured due to inhumankind meddling with natural balance. Ecological catastrophies due to the "crown" playing god.
It is us thinking that we are more than animals, that we are not animals, that we have "higher" morale that is a true delusion
We have the choice for a morale - we have the choice to control instincts - we have a choice to use our brains and think beyond our nosetip.
Sure, may not be fun, not be satisfactory, maybe unpleasant, boring etc. - but the only difference between animals and the homo is our developed brain. Wish, some would use them.
Avoiding our own natural calls and needs for a higher morale that is not supported by nature
I disagree again - if it doesn't taint your instincts, try reading about social/instinct/natural behaviour amonst mammals. Overpopulation amongst rats e.g. => infertility. Where's the "natural call" in homos? Ever read about strong protective behaviour? How familiar are you with ethology? If you were - I doubt you could consider the human race superior to ants. Why? Because their social system is far more advanced than ours.
I believe, we do not have much "nature" left in us - but we have reasoning, thoughts and we can (if we wish) differentiate, abstract and evaluate the consequences of our deeds. I, on my behalf, prefer this to gut "instincts".
I do not believe, we are the "crown", some may. I just think, we're a very young species and it is in our hands to develop or extinguish as the dinosaurs did, unable to adjust.
The key for this? Again the brain => (self)responsibility, as Womble already stated and I would add discipline, social thinking and self-criticism, observation, regarding consequences.
