Stark oversaw the Euro 2012 qualifier between England and Montenegro and sent Rooney off after he kicked out at Montenegro defender Miodrag Dzukovic.
However, he feels that Rooney's decision to walk away without protest may favour the 25-year-old in getting a lighter suspension from UEFA when the committee reviews the incident.
The Manchester United striker will definitely miss England's opening match in Euro 2012, but the straight red card may result in him missing an additional two games, pending UEFA's decision.
Stark told the Sunday Mirror: "Maybe it will help Rooney the way he acted by accepting my decision without any fuss,
"It was a straight red card. I had no hesitation. Everyone saw what happened and Rooney knew by his reaction. He accepted my decision without dissent and walked straight off the pitch.
The German referee will have little part to play in making the final say on Rooney's fate, though, as his involvement will end after submitting the match report.
He concluded: "I will submit my report about the sending-off. After that I will have no more input and it will be up to Uefa to decide what to do."
