Why don't you return it and get a Savannah monitor? They stay smaller and have less violent personalities.
You said you wanted a mean animal. I don't think you realize what you're saying. For example, a lot of people like to keep big, mean dogs as a status symbol. They think it's cool because their dogs basically scare everyone else and look mean and act tough. But, ultimately, a dog is still a domesticated animal, and a mammal (more cuddly than reptiles), and capable of recognizing its owner and perhaps even knowing, on some primitive level, that it is wrong to harm its owner.
Reptiles are completely different. This big, mean, strong reptile will have no problem turning on you as it will turning on a stranger. They can do some serious damage, too. So what'll happen is you might end up in the hospital with bad scratches and even worse bites, and then some congressman will lobby for banning the ownership of all monitors, maybe even all big reptiles, and the thousands of other responsible herp owners in your state will lose that right, because you wanted a big, mean lizard.
