[Christmas Lights]

We are talking about the same children's cartoon right?? ,I don't think the writers nor the creator ever intended for Homer to be that .In the early seasons and Ullman shorts ,he was originally just made to be an authority figure who was grumpy ,he was snappy with Marge and especially the kids ,but that was it . There's no other darker tone there,he was never violent.

Homer was based on a 1950's sergeant Major type father figure,so he sounded strict with a deep voice.


But over time the writers , wanted him to act more comical & dopey ,hence the voice actor Dan Castellaneta changing Homer's voice to sound more dim and childish,and of course slobbish.
