It's the nature of mankind.
[Infos might be wrong]
We are somewhat of a strange species if you ask me. We are social like wolves, they hunt together, they are together, they share their food and care for each other.
However we are competitive like lions, they have their pride, they have their own territory. Yes, they have their pride, but it's not exactly social, it's more like a family.
Now we, as apes. We are social, we wouldn't get so far if we weren't.
We decimate the other tribes like the Denisovans and the Neantherdals mainly because we were social, we fought together and communicated better. Because supposedly can understand each other.
Yet we kill each other, we strive to eliminate the competition even amongst ourselves. We kill for food, for territory, for mates, for fun.
We have capitalism where we enslave our own kind for benefits, but even without this system, the competition would still happen. It was there when our communist ancestors walked on this rock. It has always been there.
Our sociability is not protecting the weaker ones amongst the tribe, it's using them as a resource. The weaker provide fun, stability because you're well seen if you are the strongest on a pack of weaklings, stability of mind because some can feel better when they see someone worst than them.
That's might be why people are cruel to each other. If they bash someone enough, they will be weaker, a potential resource.
However, that's a very primitive thinking. We are to evolve. I think we will have more stability with good people among us, we will have more strength if our friends are also strong. Sky is the limit, why keep such a preserve such a dated way of thinking?
I'm sorry people betrayed you. One of the worst feeling we can have is give something that is very valuable as trust nowadays just so people mistreat us later.
You are better than these people. You understand the valuable of being a careful person. Of helping those who are beside you so you and them can reach further achievements in life.
But they are not those kind of person. They failed you because they are might be already failed beings, until they learn the importance of being caring, of leaving our competitiveness behind.
Maybe we are species that were born out of their time, or planet ...because the future right now, actually holds a daunting promise.
Sorry I actually don't even know what I'm talking about. Just wanted to let some words out.
I just want to say that you are very special, you are a good person.
