Only watched half of the video (because it's something I'm well aware of), so it might have gone into it, but another angle is that there's often villains that make good points and then suddenly take it in a batshit direction.

Like Thanos had a point but apparently never understood exponential growth and how reducing all life by any constant factor is just delaying the same result, even if his snap made 99% of people disappear (unless he snaps enough people that the population collapses entirely, which is what he wanted to avoid).

There's many other examples where reasonable starting points end up in unquestionably evil conclusions. Pretty sure it's just propaganda to make people who don't think much about things link those reasonable beginnings with "evil" in their minds.

Also there's characters like Bruce Wayne and Tony Stark who are billionaires but their stories always ignore the realities of what must be done in order to become a billionaire (ie underpay staff doing the actual work by billions). In Stark's case, they sidestep that by giving him super advanced AIs and automation robots, though he's still the owner of a large corporation, that he still benefits from despite offloading any of the responsibility of even running it to everyone else.
