What an excellent way to show you have no idea what you're talking about. Violence and gore can really drive how serious consequences for actions are, and deliver a darker, more serious tone. Something Destiny lacks. Sex or sexuality can be used to deepen characters and their interactions, as well as flaws. If used properly the inclusion of any of these can greatly improve Destiny as a whole. There is of course the chance that Bungie just -blam!-s it all up... which is probably more likely to happen.
