Nexus - that's a very good point. When I noticed the Dahmer/de Sade astrological overlap, that was one of the first things I thought of, but I neglected to mention in my first post. Based alone on de Sade being a sexual sadist, I wouldn't consider him a 'villain' by any means, particularly since sadists get such a bad rap and I'm completely down with consensual BDSM. But did he commit any truly harmful acts of non-consensual/abusive sadism (criminal acts, etc.?) - do you know? I, myself, don't actually know all that much about what he really did, but seems like the aristocracy got away with a lot in those days, so I wouldn't be surprised. Looks like it's research time for me... But, yes, it absolutely should be emphasized that he was more of an artist than a criminal, if that is the case. It's quite unfair to compare him to a serial killer, but I'm still interested in exploring if there's anything to the astrological connection between those guys. Regardless, he's pretty generally at least CONSIDERED infamous, whether or not he should be considered at all villainous.

I would definitely consider Dahmer a villainous figure, as his killings were horrendous, and I doubt hardly anyone would question that. But he's a strange case - he seemed almost more curious (taking that to extremes without taking into account any ethical questions) and lonely than he seemed cruel or hateful. Obviously, there was something very sinister going on in there, though... But, again, I'm not sure about all the details - I'm speculating based on the relatively small amount I've read about him.

That isn't what I would expect to find, though, with some overlap between their charts (assuming that it signifies anything relevant at all), as it seems that Dahmer and de Sade were coming at their acts for very different reasons (as well as their actions being very different). I suppose it does seem that curiosity was there, for both, as well as the ability to commit violence (and interest in committing violence), but de Sade's was much milder (again, and quite possibly not villainous) in expression and done for his own pleasure, while Dahmer's seemed more of a desperate impulse (with morbid and intensive follow-through) that operated in an extreme manner.

I don't know - is there anything to their astrological connections or not so much?

Going on a bit of a tangent, I always find that Dahmer's 8th House Taurus Venus (and, to a lesser extent, his 7th House Moon) really stands out to me. It's generally mentioned that he didn't typically seem violent or unpleasant or cruel until his soon-to-be victims/lovers tried to leave him (and/or until he got drunk). That he had to cling onto them and 'keep' them (his eating of flesh and preservation of body parts were attempts keeping the men, also) through incredibly twisted means seems like a pretty clear potential expression of that Venus placement.
