It's right to blame someone for his past?

It's right to blame someone for his past?
This is a 'Yes and No' question.
When you are evaluating a persons past, you have to take intoperspective as to what the person is doing NOW and what thepersons achieveable goals are for the future.

People come from various backgrounds, events, mental, physical,ecucational, parents, religion, ethnic and social conditions thatshape a person. Many of these conditions a person has no controlover.
Can you blame a person for who his parents were or where he/she wasborn. The answer is NO.
Can you blame a person for mental or physical defects.
The answer is NO.

But as I wrote above, "What is the person doing NOW."
There are a lot of examples of people who have overcome theirpast. Look them up on the internet. There are a lot of amazingstories of people whom have overcome incredible situations.
I have to admit it isn't easy to overcome a personspast.
I use myself as an example: I was born to parents with limitededucation. We lived in a 2 room stucco house with a pot belly stovefor heat, and out house for a toilet and a hand pump for water. Wewere super poor. My father was an alcoholic. I was teased and madefun of by the kids at school. Only one of my 8 brothers and sistersfinished school. My father died when I was 12. I associated withthe wrong kids at school. Actually many of the kids didn't want toassociate with me. Had alcohol drinking problems. I got in trouble.
Okay. I believe, I overcame all of this. I graduated fromHigh School. Went into the military and retired as an officer. Wentto college. Ran marathons. Have two bronze medals. Wrote a book.Financially stable. Have a great family.

Now the hard part. You ask, "It's right to blame someonefor his past?" The answer can be 'YES', if the person hasn'tlearned from past mistakes and isn't changing.
Please note I used the plural in 'Past Mistakes'.
As an example, if a person gets arrested for DUI/drugs/theft (once)and learned from his/her mistake and never does it again. Youshouldn't blame that person. It is over and done and he/she hasmoved on. I hope to better things.
But if the person continually gets in trouble/arrested forDUI's/drugs/theft/etc. (3 or more times) and still drinksalcohol/using drugs/stealing/etc., they haven't learned anything.More than likely they will continue to get into trouble in thefuture.
