Hmm it's hard to say, I would say that mostly the killings are done in a very artistic way actually, so it's not all gore and torture porn by any means. There are a few stand-out gross moments that are *really* gross, but it's not something that's happening every episode either. I think that season 3 is one that you would really enjoy if you're mainly interested in watching for Gillian, Bedelia and Hannibal have run away together to Italy and get a lot of focus in the first half of the season

And Bedelia is in the last scene of the series, she's sat at a dinner table with what appears to be a leg of something that is very elaborately prepared, then the camera comes downwards and you see that one of her legs have been amputated. She's still alive at the end of the series though, it's IMO ambiguous as to whether Hannibal has captured her or not, but season 3 did have a running thread of Bedelia worrying about Hannibal being about to eat her
