I don't usually play characters like this, but the worst one I played was probably [url=http://www.roleplayerguild.com/topics/47334/posts/ooc?page=2#post-1427846]Malag-Haramon, The Blood God[/url]. For those that don't want to read a CS, he was basically an extremely hedonistic combat/bloodshed/violence deity who was worshiped with gladiatorial bloodsport and orgies. Both of which he would occasionally participate in. He was a fun character to write for, it's a shame the roleplay died.
