Human beings have difference of opinion and like to argue in an aggressive way.
This leads to violent conflicts and loss of life. It appears that humans are born to fight. There is still some chance that their violent tendencies will be overcome by improved thinking, and make better choice on how humans resolve their differences.
when 2 or more societies, countries disagree on the values of each others communities and they cannot live as neighbours, wars usually are started to take over control.
