In the future I hope you are all considerate of reality.:You must subscribe to the Hobbesian view of man.
I do not subscribe to such a view, all my thoughts on this subject have been formed from personal experience. If you let your emotions get in the way of the big picute you do not think logically, but rather emotionally, which is devoid of all logic. Everything has an order which can or cannot be changed, but if we listen to our emotions and not our logic wonderful brains we will not come into contact with this order or change it.
Basing your actions on your emotions can be rather devistating. You say that a world without 'love' and 'peace' and 'good' things would be a world in chaos. It is exactly the opposite. A world without logic would be chaos.
