While that may be a kind view, practically it is rarely a useful one. At least for the person holding it.
Especially when power, violence, money, or sex are involved.
Yes this resonates.
I feel that stupidity is evil in the same way as that a shark might be perceived as evil. You could explain it away as "It's not their fault, it's in their nature, they don't know better" but if it's in their nature to cause people harm, if anything, it makes the label more applicable from my perspective.
I think you have things backwards. Being dumb is the default. It takes ability and effort and help to get smarter. Animals and children are dumber than us. Do you think they realize it?
Perversely many who are dumb are trapped thinking they are not dumb:

A dumb person (like a dumb child or animal) are what they are one should not attribute malice. Better to try to see things from their point of view and perhaps help them be smarter. This is what I try to do.
Your other remarks are 100% just the point above was sticking out hence my comment.
