Karna: "My mother left me the moment I was born. Is it my fault I was born an illegitimate child?
I did not get the education from Dhronacharya because I was considered a non-Kshatriya.

Parshu-Raam taught me but then gave me the curse to forget everything since I was a Kshatriya.
A cow was accidentally hit by my arrow & its owner cursed me for no fault of mine.
I was disgraced in Draupadi's swayamvar.
Whatever I received was through Duryodhana's charity.

So how am I wrong in taking his side?"
Lord Krishna replies,
"Karna, I was born in a jail.
Death was waiting for me even before my birth.The night I was born I was separated from my birth parents.From childhood, you grew up hearing the noise of swords, chariots, horses, bow,

and arrows. I got only cow herd's shed, dung, and multiple attempts on my life even before I could walk. No army, no education. When all of you were being appreciated for your valour by your teachers I had not even received any education.

I joined gurukula of Rishi Sandipani only at the age of 16!
You are married to a girl of your choice. I didn't get the girl I loved & rather ended up marrying those who wanted me or the ones I rescued from demons.If Duryodhana wins the war you will get a lot of credit.

What do I get if Dharmaraja wins the war? Remember one thing, Karna. Everybody has challenges in life.
LIFE IS NOT FAIR ON ANYBODY!!!
Duryodhana also has a lot of unfairness in life and so has Yudhhishthir.
But what is Right (Dharma) is known to your mind (conscience).

No matter how many times we were disgraced, how many times we were denied what was due to us, what is important is how you REACTED at that time. Always remember, Life may be tough at a point, but
DESTINY is not created by the SHOES we wear but by the STEPS we take.
