I need a name for a character in my short story?

A meddling creator of and participant in a dangerous medical experiment he is non the less lovable and the reader should sympathize with his plight, his last name (used with the prefix "Doctor") should emphasize the cruel and heartless monster he appears to be but his first should emphasize flip side of his persona where he is a caring friend, strongly motivated to pursue often controversial methods to cure the one he loves. I know this seems difficult but please give it a shot.
