Was Rodolphus trying to be the real-life Dr. Frankenstein? Maybe he was planning on building his dead wife a brand-new body from bits and pieces of others. He claimed that Hermione had many of the same features. Was it even possible to cut multiple bodies up to make the perfect vessel? And even if it was, how would he make it Bellatrix? Could he call her back from beyond the Veil? Or was he just essentially trying to create an inferius that looked a bit like his wife?
