Oh, I don't know. Why would they be seeking something right there if there was no hate? And there's a level of "not caring" that overlaps active hate. When it comes to dehumanising people, to feeling free to ignore the fact that someone else has as many feelings as you do, and enjoying that freedom to harm someone else, well if it isn't hate it will do just as well.
You can go too far worrying about the causes and the thinking. These men probably weren't thinking, they were doing their best not to think. Or to empathise. They were choosing to shut down the bits of their brains that could have said "don't". As people do when they're deciding to do something bad to someone else for their own satisfaction. For a few of those men the empathic or ethical ways of thinking might be missing or blunted, but probably not so much you'd notice. And some people imagine sex as a kind of secret "anything goes" zone and porn mightily encourages that.
None of us are perfect and one of the most dangerous combinations is hating or despising people plus getting something out of acting on those feelings - money, sexual satisfaction, job security, status. The men were somewhere along the righthand bit of ther NAMALT chart but it doesn't matter exactly where. Pelicot himself was way off the far end, the others not. As the psychiatrist on "51 Men" said, they weren't serial rapist types but they weren't just average either though there was nothing obvious to distinguish them from average men. Banality of evil and all that. 50-100 men who funnelled themselves along that path out of, I dunno, how many men in the locality?
So "not all snakes" but even with just a 1 in 100 chance for getting bitten by an individual snake the chances of getting bitten ramp up massively because life is not just one walk through the snake pit, life is one walk after another after another. We're going to meet the poison snakes and women do have to hope the circumstances don't add up to getting bitten. And as a society we have to try to cut down the opportunities (and by that I mean keeping the snakes away, not telling women to keep off the grass) and decrease the reward the snakes get from biting.
