In fictional worlds we see human behavior focused on the intent of the story.
Good and bad is always separated.

In real life we encounter many shades of grey in people.
There are people with a predilection for bad and others with a predilection for good.
In society, there can not be a pure utopia nor a pure dystopia.
In people, the same applies.
Nobody is purely bad and noone is purely good.
Just like society, people are a mixture of both. Some darker shades of grey some lighter shades of grey.

Wisdom is gained by experience.
Deeds define how others judge you.
However, deeds seen by one person in a specific time frame may not be the deeds seen by others over a different time frame.

Before you met someone, they might be known as caring and warm.
You experience them as hostile and rude.
That person is not good or bad, they just don't like you.

Your child is warm and loving.
In 10th grade, he gets suspended for fighting and bullying.
He is still warm and loving, his experiences outside your frame of reference are such that his reaction to certain others becomes bad.
He doesn't go to school wanting to fight but has to fight for reasons he determines at the time.
He isn't a bad person, he isn't a good person, he's just a person making choices.
Anyone can be good or bad depending on their choices.
Sometimes its easier to feed the monster than to feed the angel.
Sometimes the monster appears to be the angel.
Sometimes the angel turns out to be the monster.
Wisdom defines the angels and the monster.
Some people have poor wisdom.

We military struggle with this concept.
I know how to kill.
I have killed.
I could kill again.
Am I bad?
I choose not to kill.
Am I good?

Generally, people think its their job to define others.
If you define me on your terms does that make me bad or good?
Do YOU live behind my eyes?

In life, you encounter many different types of people.
You 'align' with some and you 'avoid' others.
Your wisdom guides you.

You see your boss as a good person.
You really enjoy his company.
Then you find out he goes home at night and beats his family.
Until you knew this, he was a good person.
Now he is a bad person.

Flip the coin.

You see your boss as a bad person.
He's mean and rude to you at work.
Then you meet him at a social function and he is warm and friendly to everyone.
Is he now a good person?

This is judgemental prejudice relative to the observer.
If you expect the worst from someone, you won't be disappointed.
This is because you focus on the bad.
If you focus on the good in a 'bad person' many times you will be surprised unless you are blinded from seeing the good by your own expectations.

So you're saying that if a "good person" saw you burn a child alive that good person would believe you did it for a good reason.

If a "bad person" saw you donate ever cent you own and go on a mission trip to help starving people around the word, that bad person would believe you are doing this for bad reasons.

I totally get it now.

So if a person saw you steal an apple to feed a hungry child, the good person sees you as bad for stealing and the bad person sees you good for stealing... or is it the other way around?

Got stigmatzm, everyone looks schetchy...

I think you made that word stigmatzm up....
