This is not a “narrative” frame in the sense of an arbitrary perspective. It means dealing with reality rather than stating ideals.
The problem here is not that we need to identify the psychopaths. We know who they are. Civilians are not dying because Israel wants civilians to die. So just stating the absolute truth “it’s awful that innocent people are dying” contributes nothing to the debate, and shouting it louder is not a morally superior position.
What matters is finding an answer to the difficult problem where conflicting absolute ideals cannot be reconciled. A war can have a just objective, but no war can be fought without harming innocents. Unless you are prepared to engage with the difficult problem of how Israel can achieve their just objective in some better way, or to present a cogent argument that they should not pursue this objective at all because the cost outweighs the benefit, Israel will (quite reasonably) ignore you.
