I think it might be- Did it have a scene in it where they went to the house and found all kinds of body parts and where he was skinning them hanging from meathooks? If so m, then Yep- I’ve mixed the two up- I don’t recall what the slingblade character was convicted of?
For murder....but dang I can’t think of who it was. Later in the show he confronts his father and turns out he had a baby brother (maybe a sister) and they made him bury it....his childhood was horrible. I don’t think there was any animal processing in Sling Blade but in the end he commits another murder which had the crowds cheering cause this POS needed to die.....lol......been a long time since I watched it but you sure did sympathize with Billy Bob Thornton’s character.
