In every Medical Drama, almost every Cop Show, basically any show where the characters often have someone else's life/future in their hands, there will come a time when they will fail and the person they're trying to save will die (or wind up paralyzed, or in jail, or some other long-term bad thing). The character will feel incredibly guilty, but an understanding friend or colleague - sometimes even the person whose life they just ruined - will insist, "You did everything you could" or "You tried your best" or variants thereof. Sometimes the character will say the phrase him/herself, in which case the "you" becomes "I."
Usually this helps, and the character is able to move on. Sometimes they don't, and fall into depression, and after a while will have another stock phrase thrown at them: "You can't keep blaming yourself!".
On the other hand, it's sometimes countered with a taunt of "Your best wasn't good enough!" And sometimes, it may still be good enough to keep you your job.
- It could be interpreted that this is what kicks off the entire plot of Naoki Urasawa's Monster. After being assigned by the higher-ups in the hospital to save the life of a famous opera singer instead of a Turkish man, Dr. Tenma tries to console himself by getting one of these during a dinner with his fiancee, Eva. She gives it to him, immediately followed by the line, "After all, not all lives are created equal." The shock of this helps him make his decision to save the life of the title character.

- In the first issue of The Power of Shazam, Captain Marvel tries to rescue people trapped in a burning building.

Her friends and family keep trying to tell her that she doesn't have to go to all this trouble and that she's pushing herself too hard, but her conscience won't allow her to let up.

- In Warrior Cats, Cinderpaw gets this lesson from Yellowfang after she fails to prevent Silverstream's Death by Childbirth (though she does save the kittens). In this case, her worries were compounded by the fact that Silverstream is from a rival Clan, and having another Clan's member's death on your hands is not a very good place to be in this world.
Yellowfang: I've spoken with Tigerclaw. He's furious about the kits, of course, but he's not angry with you, Cinderpaw. He knows you did your duty, just as any medicine cat should.Cinderpaw: But I lost her, Yellowfang.Yellowfang: I know. And that's a hard lesson to learn.

Martin, who obviously can't hear the other end of the conversation, freaks out and decides to resolve his problems with his old friend.

When they do speak, however, Pellew says much the same thing as Matthews and that dealing with men bent on self-destruction is just a cost of command.

- One of the most emotional stories on Scrubs had Dr. Cox lose three patients after giving them transplanted organs that unknowingly came from a donor infected with rabies. JD tries to comfort him by pointing out that the disease is so rare there is no way any doctor would have thought to test for it, and it would have been irresponsible to do so with the patients waiting for those organs. He also repeats what Cox told him, that once you start blaming yourself for deaths that weren't your fault "there's no going back". It doesn't work; Cox spends the next episode in a drunken Heroic B.S.O.D., only recovering when JD instead tells him that he admires him because after all these years of watching people die "you still take it this hard."
- Said a few times on Emergency!. One example is Roy and Brackett trying to assure Johnny that he and Roy had done everything possible to save an officer friend of John's, despite a busy radio making communications harder to get through.

- Commander Shepard from Mass Effect gets this quite a bit throughout the trilogy from subordinates and friends, especially in Mass Effect 3 as the bodies and defeats pile up against a near unstoppable force.

Liara: You couldn't possibly have been prepared for this.
- In The Legend of Heroes: Trails of Cold Steel II, Towa tells Rean that he did all that he could to bring Crow back to the academy.
- ''Decision: One of the lines randomly spouted by militia at the end of a level is this trope, despite having no relation to how well you did on the level.
- Limyaael's Fantasy Rants: Limyaael advise against this in writing. She says that authors should not invalidate guilt on the protagonist's part (as in) and should keep it genuinely ambiguous as to whether the protagonist could have made a difference. This opinion being expressed by other characters is fine, but if an author constantly makes it so that the protagonist's failures have no consequence ("It doesn't matter that you couldn't/didn't save him from the housefire, he would have died that day from Lethal Disease #9567 anyway!") the protagonist verges into Mary Sue/Boring Invincible Hero territory, and the story loses realism and depth.
- After spending half of Ninja Turtles's fourth season in a guilt-induced funk, Leonardo makes the first step towards recovery after he admits this to himself.
- Parodied brilliantly in The Simpsons — "You can't keep blaming yourself. Blame yourself once, then move on."
- The Simpsons did use it straight in the ep with the operation on the dog when the vet throws a dead hamster into a garbage can. The garbage can has a little basketball hoop on it -- it's clearly not the first time he's chucked a small dead animal into the garbage.
- Parodied in Xtacles: "You did everything you could.....from inside this car".
- Quoted by Kopaka in Bionicle: Mask of Light, when Gali manages to successfully cure Tahu with her water powers after the latter has been poisoned and brainwashed by the Rahkshi.
