Kane, 20, was arrested in his hometown of Buffalo, N.Y., at approximately 5 a.m. ET following an alleged violent dispute with a cab driver.
"Sometimes you get yourself into a situation that you wish you didn't," Roenick said Monday morning on the "Waddle and Silvy" show on ESPN 1000. "I think at that time of the morning he's got to be responsible for where he is, what he's doing and what he's doing to get home. I really think it's an unfortunate situation."
While the Blackhawks said they're standing by their young star, the NHL is looking into the incident. The attorney for the cab driver said the incident has been overblown.
"I was really surprised [when I heard about the incident] because it's very much out of Patrick's character from what I know of him," said Roenick, who retired last week after a 20-year career. "From when I've talked to him, I know he likes the fast lane. He likes to go out and enjoy himself. That's what all kids should be doing. He should be experiencing a lot of fun things at a young age and living his life as a professional athlete.
"I was surprised, but then again kids make mistakes. And sometimes they become better people because of that and I hope that happens with Pat."
Roenick believes the incident could teach Kane a lesson.
"I think Patrick will be the first one to say he's sorry," Roenick said. "He'll be the first one to admit he was wrong. And you know what, he's a kid.
"I mean it's one thing to realize that there are people out there that are going to take advantage of you. There are going to be people out there that are going to try to make a name for themselves, or at least get money in their own pocket because of fame. And if he doesn't watch his back, and if he doesn't prepare himself for all situations, he's not invincible. I think this is a going to be a very big lesson learned for him."
