Thing is, if one of the Holmeses gets on his case, they will spot what everyone else missed nearly immediately, and none of them would pre-suppose a limit of human depravity (since many of their cases already involve things somewhat like that).
Now, it's slightly possible that Lecter could somehow toy with Miller-Holmes to get him to fall into drugs (his addiction and recovery is a key point in the show, after all), but that's something that would be really hard with his current supports. And it wouldn't be fast enough to stop him from catching the guy, in all likelihood.
