Seemed careless more than it was malicious. Wasn't even looking at Perrault, and even followed the puck afterwards and wasn't focusing on the scrum. I don't think there's really any intention to injure there, it's just typical Gudas being a brain-dead moron.
Don't get me wrong, you are still responsible for your actions out there and Gudas deserves to sit, but the difference between a 2-to-3 game penalty and a 23 game penalty is intent to injure, and I don't see it here. I hate Gudas as much as the next fan, but he probably gets a couple of games (2-3 if it were a regular player, maybe Gudas gets 4-6 because of his history of being a dumbass) and a stern talking-to from the league and his team about being an idiot, rather than a big long "make an example out of you for being evil" suspension.
It's not even comparable to any of the famous head-slashes (McSorley, etc...).
