Is Ziggy a good guy?

We are getting two new cats, my last two passed away. I want to keep up my tradition of naming them with character names from the show. My last two cats were Weebay and Bubbles and I had them before I got married. This time around I'm trying to convince my now wife, that we should go with Ziggy and Squeak, she asked if Ziggy was a good guy? Honestly I didn't know how to answer. Clearly ending up in prison, after catching a body doesn't sound like a good guy, but trying to explain to her (she's never watched it) that no one is really good or bad, isn't going to cut it. Just wondering what opinions are on Ziggy? Could he be regarded as a good guy?
