Conscience has something to do with guilt and blame, doesn’t it? It at least deals with the attribution of harm, and my point is that attributing the ‘increase in chances of harm’ to protestors a bit misplaced, since it’s Biden who has the agency to act against Israel, not the protestors.

The protestors are simply modeling the behavior they want to see from Biden: withhold support (or threaten to do so) from Israel until some concession is made. Either Israel will relent or we’ll reduce their ability to continue their assault on Gaza.
