Nearly all adult humans have a conscience; which varies according to our upbringing and the society we occupy.The greatest allowable freedom is that enjoyed by western secular democracies. They have been shaped by Christianity and now they shape Christianity and seek to make life for everyone more tolerant.
Oppression and control comes from the fixed rules of ideology or religion. Once an individual allows his free conscience to be controlled they lose their humanity and can do anything. This is the radical mind-set trap that it is possible for anybody to fall into.
