The world of Fallout is full of death, destruction, and morbid humor based on the post-apocalyptic setting, where humans are basically up Rock Creek without a paddle.
Every game in the series contains a few quests that are seemingly impossible to beat without killing a character, so how does a pacifist survive in that dog eat Dogmeat world?

According to the guy who achieved the seemingly impossible, Kyle Hinckley aka The Weirdist, the key is to create a character with such a high Charisma score that enemies would rather turn against each other than attack the character.
Kyle's unprecedented, and completely documented on video, no kill run has revealed another layer of complexity that even Fallout 4's game director Todd Howard didn't know about.
