The Spaniard suffered his only defeat to date at Roland Garros in the fourth round against Soderling last year as the Swede made it through to the final, only to lose to Roger Federer.
He will be facing him once again for the finals this time around.
"I never believe in revenge," said Nadal. "I believe in trying my best in every moment and if I lose, I lose, and congratulate Robin because he did better than me, as quoted to BBC Network.
"But I go on court trying to play my best tennis and thinking about Roland Garros, not thinking about Robin. For me, revenge doesn't exist in one match, and especially when we talk about the final of Roland Garros," he added.
A victory on Sunday will take Nadal back to number one ranking in the world and leave Federer one week short of matching Pete Sampras's record 286 weeks in top spot.
