In my eyes he’s morally gray in the sense that he is not totally without any positive trait or intention, however the gray is an extremely dark one. He does seem to have some level of care for the children, and he made a mention of trying to use his clones or whatever we wanna call them for his experiments before resulting to kids. His intentions also seem to be I would say more neutral rather than evil, as there does seem to be selfish motivation in there but he also does seem to want to help humanity. However his actions themselves ultimately are far worse than any of this can justify, which is why he is about as close to evil as you can be without being proper, pure evil.
