He did kidnap and rape Persephone, but that’s pretty much the same level of dickishness seen in all the Greek gods (Leda and the Swan anyone?)
I like the idea of Tartarus having a sort of infernal jailer, but then the moment they mentioned Tartarus on the show I knew we will never find out. Tartarus is basically hell, and the idea of all the really nasty monsters being locked up there is too interesting for the writers to actually do anything with it other drop a couple of references every now and then.
Because apparently the writers love to tease those of us with an obsessive lust for more world building.
