Anyone knows which horror movie this is?

I'm not sure if this is a Swedish movie or not, but anyway...

I remember we were watching some sort of moral animated horror movie back in the early 90s at school, which was very creepy for our age (7-8).
It was about a group of kids that were often up to some sort of mischief, and they were often taken to a scary judge who had a skull on his table - and everytime he laughed (because obviously he was rather pleased with punishing the kids), the skull laughed as well.
In the end of the movie one of the girls was blindfold and forced to pick his boyfriend from the rest of the children, and if she failed, they would all die.
The film ended with a house burning down, and I think the judge was burned inside.
Everything had a very dark and creepy atmosphere, almost like a nightmare.

What is the name of this movie?
I can't find it anywhere no matter what I search for on Google.

Terminator 2

Jesus, that sounds creepy. Now I want to know what it's from too!

Haha yeah, I'd love to check it out.

Try searching for animated horror films before the 2000s. That might narrow your search down since there's not many horror films that tend to be animated.

Thanks, I'll try that.
Actually I'm not even sure it was an actual horror movie, but it was some sort of moral stuff presented in a slightly creepy way, teaching children not to lie or something.
My clearest memories are that the main characters were children about 10 years old, and that they sometimes saw that judge guy who laughed at them and punished them.
