is it normal its hard for me to have empathy?

Same I have had alot happen to me when i was a child. It has effected me greatly and i am happy being the person i am today I hate people trying to suck attention out of the smallest things especially when its something they had complete control over.
I have changed into a "criminal" as you can say i dont know if your classed as one unless your caught but anyway.
Through the ages of 16-18 (I am 18 now) was when i commited crimes and no they arent as small as stealing or vandalism even though they are the smaller crimes i have done. Most of what i have done is Arson.

Anyway il go down the list of what type of person i am.

-No sympathy for anyone.
-Lack of emotion.
-Very low sex drive.
-No needs for relationships.
-Prefer to be alone.
-Thinks about everything.
-Understands situations more because i dont feel emotional about them.
-Pretends to be a nice person just to fit in.

There is more but i cant be assed listing them. I usualy wonder if im this way because of the stuff that has happened in my childhood. Are you like me or do we just share the same lack of sympathy part?

And I apologize for talking about it but i dont share my life or who i am with people i know so i talk about it where people dont know me and most likly wont be entering my life.

People even on this site have said im not normal when in reality we just have a different idea of whats normal. I know im normal.
