Honestly, good. There's a big part of me that likes guys on my team to have a reputation. It can get into peoples' heads. You'll be skating down the rink, running down the field, standing at the plate, driving to the hoop and there will be a part of your brain more focused on if he's going to defend your offense or just take you down by whatever means necessary.
Guys like that fit into good teams. Claude Lemieux was a horrible, horrible man (ask Kris Draper), but he was a successful one. Cooke's NOWHERE near as talented, but he fills his role. Intimidation.
I'm too cynical to care about my guys being Lawful Good Paladins. I get that with the Pirates where I watch naive, idealistic young men get tortured by the aura of defeat to the point where only the best can even hope to have productive careers elsewhere (for every Jason Bay, there are many Ian Snells). I want murderers who win. The rule of sports is that you love those guys when they're on your team (unless they descend to the level of "pathetic fuck who offers nothing but cheap brawling") and want them killed painfully and publicly when they're on another team.
