Addition (argument) to Blog #5:What did Margaret do?

This is an addition to Blog #5: What did Margaret do?. Please see it first below this post.

I think more that the killing of Francis Macomber was intentional. It was done possibly so that Margaret and Wilson could obtain money from Francis, and so that they can have a romantic relationship without Francis' interference. To start, when Wilson accuses Margaret of doing the killing intentionally, she says "Stop it" rather than denying the accusations. Also, Wilson says sarcastically (given the highly differing context of what he says before and after) while informing Margaret of what she had done "'Of course it's an accident'" (last page or two of story), she continues to tell him to stop, as if Wilson is mocking her and Margaret is asking him to stop.
Wilson and Margaret, during the night before Francis' death, may have been devising a plan to kill Francis. What is suspiciously hinting at this is when, the next morning, Wilson asks Francis whether he did "'Sleep well?'" (Francis would not have slept well if he knew he was going to die the next day.) This situation of conspiring against Francis is made suspiciously more real when Wilson says, right when they were getting ready to kill the buffalo, "'We'll leave the Mannlicher in the car with the Memsahib.'" This enables, whether or not she wants to, Margaret to use a gun, and it seems that this was planned so that she could possibly kill her husband while making it look like an accident. The part that looks like an accident is when she seemingly aims a buffalo charging towards Francis, but instead hits Francis. Now, it could be argued that in a moment of panic, irrational decisions tend to be made, but in this case, the very fact that Margaret chooses to shoot in the general direction of her husband probably without experience even though Francis, with some gun knowledge, and Wilson, a professional is there to protect him seems to show carelessness and intent of shooting Francis more than a genuine attempt to save her husband and an accident. Her fatal shot, as she had probably no knowledge of gun use, was probably a lucky (for her) shot.
