Great point. I think it's easy for many or even most to rationalize or distort truth when the struggle is not directly felt or when the wrong doing is out of sight. In my humble opinion it can take real awareness and thought to consider others from a distance in situations where yourself or people you know and love could benefit.

Sorry for the aside but this gets me thinking..

Even in daily life it's easy to observe someone not caring or even supporting malevolence when there is no consequence to them, and then when the situation changes, when they do not benefit or might even face the wrongdoings themselves, of course they immediately change their position. 

Imo that just perpetuates itself in coddled, safeguarded states. And i think it's most common and even likely in people who seemingly haven't dealt with adversity, justly due consequence, suffered or been wronged themselves. Like there is a lack of awareness, an immature ignorance.

And as mentioned above when incentives lead to benefiting from the wrongdoing it gets even uglier. The old "show me the incentive and I'll show you the outcome" can be pretty dark, especially when people don't personally know the other people involved.

I think many people dismiss religion and are unwilling or not interested in studying theology.

A way some might be able to see the concepts of good and evil or even the ideas of angels and demons existing in at least some sense might be to see them as describing words.

For example, explaining that all words are approximations of our thoughts. Obviously an ice cream man isnt actually made of ice cream and if you say something or someone is cool, you are commonly not talking about temperature, same as if some is "hot". 

The same is true if you call someone a life saver, a hero or an angel. These are approximations to describe the truth you perceive, same with perceiving someone as a demon or evil. These aren't imaginary fictitious things, they are approximations of truth when used sincerely. And they are worth integral examination when used by educated rational individuals, not just terms thrown around to hurt people or used for petty name calling.

If you are sincere after you touch fire and realize fire is hot, you burned yourself, that injury is bad and hurts. There is knowledge to gain from the experience, consequence and realizing that truth as objective and critical to learning.
