Why?

Today I sat and pondered the universe
Questioning our very existence
And wondering if life is just a curse

I look around and what I see
Is selfish people who stop at nothing
And say its all about me??

I see how we blame others
When we have done something wrong
Sometimes we even turn against our own mothers.

We become jealous when others have more
And ohh what a sin and how I would just die
If I were to ever become poor.

We put other people down
Because they are different from us
It gives us joy to see them frown.

We lie to those that we trust
Never knowing if they are truthful or not
Fending for yourself has become a must.

We cheat on the ones we love
For no reason at all
We let people in and care just to give them a shove.

So I guess all im asking is why?
Why do people act this way?
Just know it will get worse, as the days go by.
