Who said "How can anything, even a fight for justice, born out of
hatred, ever be good?"  Asked by P Rajeswara Rao of Chennai, India.

Here is avery similar statement by Nobel Peace Prize winner Elie Wiesel: 

"Nothing good, nothing worthy, nothing creative can be born of hatred.
Hatred begets hatred. That is why we must keep it from our doors, send
it away, repel it, disarm it?vanquish it before we even see the shadow
of its shadow."

Parade Magazine: When Passion Is Dangerous, by Elie Wiesel (4/19/92)

I have come across other citations to Wiesel for the same or similar
quote, so I strongly suspect that Parade wasn't the first or only
published source for it.

Might this be the quote you remember?

No.  Definitely not.  RajeswaraRao
