Of course. And Chaos consumed Galaxia making her do evil things, and Beryl agreed to be Metalia's servant in return for evil power, and Pharoh-90 converted the DNA of those desperate to save their loved ones. But I'd argue these barely sentient sources of "evil" aren't usually who the Sailors interact with until a brief moments at the end. Beryl had a choice, Black Moon had a choice, Galaxia made the mistake of assuming she could consume and control all of Chaos, and Nehelenia made a choice to smash her own dream mirror. In making these decisions, whatever their motives, they became the real monsters.
To look at it from another perspective, think of an aggressive venomous snake. It bites and kills everything it sees. That's just what it does. Wiseman is the snake, but Black Moon are the people that consciously choose to use the snake as a weapon to carry out their ill conceived plans.
You can take this analogy with a lot of different things.. climate change, inequality, disease spread. Just because you are not stopped from doing something (such as not wearing a mask) does not mean that it is not hurting others (you may be in the early stages of having a disease and spreading it) and if you are aware of the facts you can still choose to make a difference, no matter how small. I'm not here to preach, I went shopping today without a mask. I'm not proud of it, I left my mask in the car by mistake, but when I realised I didn't go back to the car to get it... I could have. Black Moon could have rejected Wiseman/Nemasis.
Also Beryl did to Mamoru basically what Demande tried to do to Usagi. Beryl was even better at it than Demande. But this thread is not about gender stereotypes.
