History always repeats itself because , well ; history never dies so that ideals can die peacefully. The tyrants are patient and are always laying in wait , building and structuring a system they opine is foolproof . They try to predict the human element and classify it.identify the opposition , decide how to eliminate the opposition or punish them into submission. Evil is not a singular person ; it is in itself an ideal. People come and go but the ideal of evil is persistent . Maybe evil is a virus that lives in the brain of the infected. It’s been around forever. I don’t purport to know the reason people become evil, it is fun to think about when you have plenty of specimens with fanatical cohesion. Can’t all be bad childhoods .
