Hm, it was sort off like that with Hellsing, plus their own personal re-writes where they are trying to paint Alucard as someone who made a deal with Satan so there won't be other monsters like him, while in the source material it blatantly states he only accepted the offer because he was a broken coward who lost his faith. It was actually one of the key things of why The Major believed he was better than Alucard, since he denied this offer when he was close to death and wanted to remain human, something TFS pretty much cut out and went on full re-write mode thus giving us the "Alucard+God+Satan Skype call "comedy" hour".
