yes but you did say a sword can be used responsibly, but seem resistant to the idea that lasso can be used responsibly as well.
Cale pointing out how dangerous the lasso is is also common sense. Of course it's dangerous. All superhumans and their powers and weapons are potentially very dangerous if they abuse them. Diana is not a character who would, and Cale is just projecting her cynicism and envy onto her to justify her actions. Her pointing out the problems is nothing to take note of to signal writers not to use it.
