Marshal:
Kate steps back inside the general store, finding the family that runs the mercantile all gathered behind the counter, watching the entrance fearfully for any further danger. Once they understand that the peril has passed, the father and mother offer anything within the store to Kate that she wants in gratitude for her saving their son. Kate learns that the store doesn’t have any saws in stock, but can offer her a pair of unused axes.
Kansas Kate read the room, figuratively speaking.
"
Ah don't need ta keep th' axe, jus' borry it. But if'n ya wants ta do me a favor, send them two-" She directed her remark to his (presumed) wife and son. "
-out and about fer an hour or so. But you, ah need ta borry. Also, let's borry that there soap box."
Assuming compliance, Bloody Kansas Kate set to her grisly, but necessary, work. These horrible men who abused children needed to not just be defeated, but utterly demoralized. The clean death by one well placed shot was something Graham may have deserved, but not this piece of excrement. The soap box would make an executioner's block.
Evans was not going to his grave in one piece. Given Kansas Kate was not practiced at this, it was going to be a bit messy.
She did feel a little bad about making the husband clean this mess up, but, looking on the bright side, it would give him something grisly to protect his family from. Such was the questionable logic of Kansas Kate.
