good or evil!?

renfield is very questionable like sometimes he is very crazy and evil but othere times he is a good guy like he went from wanting to be just like dracula to kind of questioning his way of life after he found out that one you kill someone or something you take its soul. that really got to him and then dracula beat him up and he told everyone that was hunting for dracula information about him. so kind of renfield when from being evil to good witch is weird because i thought he was draculas most loyal follower.
