Kinda bringing up an old dead topic. I'm just some random person looking more into the incredbly open ending left on the Anime, I just wanted to point out some things I noticed from what people where talking about, of the glove, and why he's not dead, and the whole control thing.
If you notice, when Integra is on the operating table, remembering her first incounter with Arucard, you see right as she's standing infront of the door leading into the cell where he was, there's a certain symbol painted in blood on the door. Which, coincidentally, is the same symbol painted on his left glove. He certainly has pretty insane powers, and it wouldn't be that hard for him to rip a straight-jacket open (like he eventually did), and it certainly isn't that hard for him to bust down a wooden door. So why couldn't he just escape? He also seemed quite arrogant with the girl until he was convinced that he was the decendant of "her father". In which case, he essentially becomes whipped. He could wear anything, but why does he wear that particular symbol on the glove, which incidentally is the same symbol that kept him locked inside that room? And after he asks for permission to use a higher power-level, if you notice, once the transgression to a higher-level starts, that symbol begins glowing red.
The devil's in the details; no pun intended. Either that, or I'm maybe trying to hard.
