Does this Trope exist?
The Hero, or some other character, takes issue with guns. Other weapons are fine with the hero. Hurting the bad guys is fine, but if you do it with a gun specifically, then the hero will give you an earful.
I am thinking specifically of things like Doctor Who, where the Doctor condemns the use of guns, but will happily do things like activate the self destruct sequence and blow up the Daleks base (and the Daleks inside) without thinking about it.
Also to a lesser extent Batman will happily use weapons like Batarangs, but guns are forbidden. (Side note: This is separate from Batman's "no killing" policy as he is often objecting to the gun ITSELF, whether the gun was used fatally or not).
