Actually you are way off base. See first nobody claimed to know what would have happened only the potential. Bear spray will likely never kill a bear and can never be as successful as a firearm where even marginal calibers have effectively ended attacks and killed bears. Second, lets compare the outcome. With the Sitka incident the guide fielded bear spray and got chewed on just like this guy that did nothing and you called it a success. I and others pointed out that if that's what success with bear spray looks like,... no thanks.
