Oh, this topic is close to my ken of knowledge....
Being a vampire would definitely have it's advantages and disadvantages.
On the plus side, you'd be nigh immortal, because there are ways that a vampire can be destroyed, so you wouldn't be going to the beach and work on your tan anytime soon. Depending on what mythos you follow, you wouldn't be able to visit anyone without an invite, cross running water, bear the sight of crosses and garlic, be able to tolerate a bouquet of roses as a gift or consume food and drink. On the plus side, you would have a set of preternatural and supernatural gifts and talents, such as thought control, mesmerism, flight, strength, speed and transformation, all good tricks to have.
On the bad side of things, you're going to be around forever, so the people that you know are going to die all around you. The other vampires will be with you forever, but damn are those relationships stressful and full of a never ending stream of drama for your mama. Backstabbing, rumormongering, muckraking, mudslinging, politicking and vendettas are going to be running all over the place, so you wouldn't know who to trust in the long run. You'd be a former shell of yourself, not able to feel what you used to feel quite the same way. You'd have a recollection of what they were, but over time they fade or distort into something that only resembles a macabre version of that feeling. Not exactly healthy.
Then there's the diet. Nothing but blood, and it'd be a terrible kind of hunger you'd get that feels like your stomach is being kicked. Get carried away with that and you'll be a glutton and call a lot of attention to yourself. What if your hunger started to focus on a specific kind of blood, the type that's not very common, like virgin Sicilian men? Fly all the way to Sicily, or hope you run into a Sicilian here in the states?
Now if there were a problem with them in town? Yeah, sure, I'd be tempted, maybe even curious. Ultimately, though, I'd have to fight against them. I have a sense of justice, I suppose, and if they were killing my friends left and right, dammit, I'm stopping them.
