HEY REMEMBER HOW SAM WINCHESTER ALWAYS AND FOREVER WITHOUT FAIL, NOT ONLY LEARNS FROM HIS MISTAKES, BUT INSISTS THAT OTHER PEOPLE LEARN FROM HIS MISTAKES. YOU KNOW WHY? SAM WINCHESTER IS BETTER THAN YOU

You know why else? Because he doesn’t want people to feel that hurt. The biggest monster for Sam to face has always been himself. Sam has fought the most against inner pain: sorrow, emptiness, loneliness. He wants people to learn from his mistakes so that they don’t have to feel pain in the ways he has always felt it. He knows what it feels like to be filled up so much by hurt that if feels like there’s nothing inside at all.
