Kids, like adults, love it when bad things happen to bad people. So Disney films always make sure the villain gets what they've got coming to them in the end. And, sometimes, Disney gives them what they had coming, and then way, way more.
As happy as they were to give us the occasional nightmare, Disney's favoriete way to misshape our world view was to jas classic stories in a suffocating saccharine wrapper, damning us all to a lifetime of naivety.
