Games have been playing with death for kicks pretty much since the medium existed. From point-and-clicks mocking you for managing to die, to platformers having elaborate and hilarious death animations, it's long been established that dying in a video game can be funny.
Similarly, plenty of enemies you face die in suitably comedic ways - although this hopefully doesn't include you tea-bagging them, because they deserve to die with some dignity.
However, because so many video game deaths have been established as funny for so long, sometimes we don't recognise how messed up they are. Your fond habit of murdering Sims is hilarious at the time, but if you explained it to someone who had never played a video game before, they'd probably worry about you a whole dang lot.
Comedy is often a matter of perspective, and it means there are a whole lot of funny deaths that, when you think about them for too long, actually are maybe more disturbing than funny. But don't worry - they can probably be both at the same time, if you only put your mind to it.
