Inequality is the goal
Overview
Power does not exist if everyone has the same power. Wealth does not exist if all have the same wealth.
It is our animal nature to raise higher than others, this can easily manifest in evil acts as people justifying evil acts in their pursuit to have more than people around them.
Like most animal natures that evolved for survival in harsh conditions, in times of abundance for good people this pursuit does not genuinely make them happy.
Evil people want power over other people so they can perform evil acts without consequence and satiate their desire to have more than the people they exert power over. To this end those in power do not want equality, their position of power only exists when they hold and maintain an inequality over others.
This becomes a primary driver in their decision making, rather than working to a common good they look for ways to enrich themselves and keep the majority powerless.
Rise and fall of societies
New societies are often born out of an uprising that overthrows a leadership whose greed and disregard for the population has become untenable.
A new system with new leaders is installed however the uprising is often led by people who themselves want power and see revolution as a way to achieve it, or if led by righteous leaders, evil will gravitate towards the newly created positions of power and take control.
Over time the excesses of those with power grows until the population cannot take it anymore and a new revolution happens.
Dangers of technology
Those in power attempt to enact systems that make revolution impossible, in the past their greed has exceeded their ability to control the population but new forms of technology such as surveillance, controlled distribution of wealth and resources, and for example un-manned lethal enforcement give evil leaders tools never before seen in history.
The historic cleansing of excessively evil leaders through revolution might not be possible in the future. The Izara Community is an attempt to create an alternative where evil has less opportunity to oppress good.
