What happens when your little sister marries Satan? It appears you have 3 options:
1. Since he is now a member of the family, you accept him for what he is and welcome with open arms. Start hanging out with him at family functions, heck, maybe even go on a vacation with him from time to time. He's part of your family, so you now must have his back at all times.
2. Despite marrying your sister, Satan is still the Devil and that cannot be forgotten. There is no way to sugarcoat being the leader of all evil, so you cannot forgive (let alone forget) the billions of atrocities he's committed in the past. Sure, you may give him a Target Gift Card at Christmas, but he is still Satan and he can never be your friend.
3. Compromise. Sure, he's the Devil, but now he's your devil, and while you cannot look him in the eyes without thinking about evil incarnate, he does make your sister happy. Maybe share a beer with him on holidays, but he's not a close friend.
I'm sure you know where I am going with this. How should Wild fans treat Matt Cooke? Me, I can't get past Option #2. Such media scribes at Michael Russo argue that Cooke has changed; that he is not the cheap player he was up until a few years ago. I'm not buying this. Matt Cooke is Matt Cooke, and even if he has changed (really?), I cannot forget his past. Good signing? Probably, it fills a need on the team, but Wild GM Chuck Fletcher blew it on this one. Ignoring the Wild's past to fill a need is not a good thing. Even if your new brother-in-law brought you a 6-pack of Surly Furious, I would not drink it. Who knows what kind of shit Satan added to the brew, right?
