Keane's second-half doubled enabled Villa to triumph 3-2 as the on-loan Los Angeles Galaxy striker marked his full debut with two superb strikes in a thrilling Barclays Premier League encounter.
But even the boos directed towards him by some Wolves fans did not tempt Keane to show any disrespect towards the club where he started his career, and he said: "I had wonderful times at Wolves and they are a club that looked after me as a kid."
He added: "I'll never forget, they did so much for me. I've got a lot of friends at the club still and it's always great to come back.
"I'll never celebrate if I score against them. I never celebrate when I score against any of my former clubs out of respect.
"But you have to be professional, do the job for the team that you are with, and that's Aston Villa.
"You have to put everything to one side and concentrate on your own job."
Keane looked sharp in his first start since the conclusion of the Major League Soccer campaign.
He said: "I feel good, I feel sharp, this was my first game since December 7. I've felt good the last few weeks in training. I'm feeling sharper and sharper and you saw that against Wolves.
"As a striker, I'm judged on goals. But the most important thing is the three points for the team and helping the team push up the league. I'm only here for a short time so if I can help in any way possible, then great."
