Aggression is such a basal trait which humans possess. What purpose does it serve apart from disturbing others and our own peace of mind? NOTHING whatsoever.
When people are angry, their reality comes to the fore. They expose themselves as their mask gives way to their reality. Id surpasses the ego. Humans can be crude. Yes, that’s true.
All of us are taught to be ‘civilised’ and ‘how to behave’ but most often than not, that’s not our true self. Animals like dogs & horses have unconditional love & loyalty as their prized traits but most humans, sadly don’t have them. Animals are better off than us in so many respects.
