The people killed in Lawrence, Kansas were in killed in retaliation for Jayhawker raids into neighboring Missouri, where they did the exact same thing. Again, nothing wrong with retaliating against someone who harms you.

The twenty two men hanged in North Carolina were hanged for desertion, another crime punishable by death at the time in the US army. Again, no wrong hangings here.
