I love Snoopy, but I also have a soft spot for Peppermint Patty as the "misfit" of her group. The arc where she sees the little red-haired girl that Charlie Brown always swoons over and breaks down crying because she feels like she'll never be seen that way is one of the most legitimately touching moments in the entire series.
Kill 1 man: You are a murderer. Kill 10 men: You are a monster.
Kill 100 men: You are a hero. Kill 10,000 men, you are a conqueror!
