It's equally funny how both analogies are limping on both legs so badly that I'm not sure they really help making a point in the first place.
Points of view, hm?
How so? If the player has no investment in the character whatsoever, you kill the character off, he grumbles a bit because of the inconvenience and rolls up the next one (probably already prepared, if you have a high fatality rate.
If the player is very attached to the character, and has fleshed it out, drawn a potrait, wrote a lengthy (and preferably actually good) storyline, and you then kill the character off, then he is going to get very annoyed, grumble loudly, consider you an ass, and won't get as invested in the next character.
Death in RPGs is perfect when it never actually happens, but if there is the credible illusion that it lurks right around the corner. Just like in movies, books or pretty much any entertainment out there.
Exemptions can be made for good death scenes (which don't have to be heroic, depending on the character and player), or if the player made a string of really bad decisions, and agrees himself that they were bad. Note how this usually doesn't apply to rolling a 1 on your Fortitude save.
Otherwise, you only end up bothering or angering your players. And given that the whole thing is a game, and a DM is not supposed to be the opponent, but more like the ally, the guide, of the players, that is pretty much the worst thing you can do.
DM's who enjoy seeing "their" monsters kill the players would usually be better off as players themselves. Not necessarily in all groups (I won't go that far), but in the group that is usually assumed in DM guides.
