Spoilers ahead, obviously.
Fallout 3
The "good" ending as a reward for doing everything right is basically suicide for the greater good.
Even if you have a specific NPC follower who can do the same thing unharmed, the epilogue text and voice-over basically calls you a coward for making the rational choice to have him do it and pretends that it killed him even though, as established, it doesn't harm him at all.
