Every seems to be on the killing an animal as not being that bad, so he isn't that bad. I am more concerned about 2 aspects myself.
1. He bankrolled, and pretty much ran a multi-state organization for illegal activities and put up a shell company to cover it. The fact he went through the trouble of the cover shows he knew he was doing illegal activity, and went through allot of trouble to hide it.
2. He didn't just kill the animals, he purposely torchered them. He killed them in slow painfully ways, just for the fun of it. I have seen allot on TV and INTERNET saying someone in the NFL is playing after Driving Drunk and killing someone, so he shouldn't be punished. While I am not condoning drunk driving, there was no plan there to kill or torchered anyone. So while killing a person is much worse than killing a dog, dint think there is a direct comparison. The WR for Panthers that hired people to kill his kids mother would be a closer comparison in my eyes.
Basically what it comes down to to me, isn't that he killed dogs. It is that he ran a criminal organization. I dint see how he can be considered a good person after doing that. Of course, most people that know serial killers say what nice people they are too.
