I'm going to interpret poorly educated as badly educated as opposed to just not.
Imo the best sign of someone who has been brought up wrong is a total inability to tell the difference between what is legal and what is moral. Don't smoke weed because its illegal. Those homeless people shouldn't have slept outside if they didn't want to be arrested. Nazis should be allowed to march in the ghetto. I've heard all of those from people that have been raised wrong. They don't have any capacity for care, and they're basically just robots fullfilling whatever function they've been told is expected of them. Their hobby is watching tv. They have a wife that they never talk to.
Empathy is part of being educated. A capacity to consider the perspective and emotions of others. We're supposed to be taught that in school, but the amount of people who grow up to be like this shows how badly we are failing.
One of the fastest ways to garner dislike from me is to say something disparaging about the homeless.

I remember a NSFW example to highlight this difference:
Someone goes to a market and buys a frozen chicken. Then the person goes back home, use the frozen chicken to masturbate. And then throws it into the trash bin.
Is this moral? Probably not, depending on your moral premises (it is for me). Is this legal? Yes. Should it be illegal? No.
Under my moral premises, that you may or may not agree with: he's wasting the work of other people, a potential source of food, and the life of an animal for the sake of something that could be achieved with his own hands, literally. That wastefulness is what makes it immoral for me.
Other people however might consider this immoral as it's masturbation, or because using dead flesh to do so is taboo.
I like this example however because, regardless of the reasons, there's a high chance that someone will consider it immoral. And yet even then it's hard to claim that it should be illegal.
