humans

I have seen people who are numb
I have seen people who forget to enjoy life
I have seen people who don't know how to rejoice nature
I have seen people who don't look
like human
I have seen them in my childhood but i was contemplating and asked myself why ?how?they have become like this
Everytime i see them i still find the same trait ,they were so difficult to put in to any classification
After passing my medical degree now i knew they exist !i can now classify them
These people aren't fit for society But society accepts them
They aren't fit to start a family , they kill others emotions, ruin relationship and leave a question for others like me in their childhood to know how someone can become like this ?are they real? Can human exist without emotions and existential questions like this
All they have ever did is to do their chores
All they ever felt in their hand is paper
All they have ever dream is money!
