I think the dialogue between Lexa and Clarke in Spacewalker is very telling how the Grounders think:

Clarke: "Show my people how powerful you are. Show them you can be merciful. Show them you're not a savage." Lexa: "We are what we are." Clarke: "Then I'm a killer. I burned 300 of your people. I slit a man's throat and watched him die. I'm soaked in Grounder blood. Take me." Lexa: "But Finn is guilty."

One was war (not guilty), one was murder (guilty).
