Morality and Weapons

Not unlike "C"ameras...

I don't understand why that's even an issue. For one, if you aren't willing to kill someone with a weapon, be it a gun or knife, don't train for it. Use your hands to incapacitate them. Why are you asking whether or not it's ethical to use a weapon you've been trained to use? Sounds like a waste of time training for something you morally object to.
