Exactly. It’s not a choice between “murder innocent civilians” and “do nothing”; it’s a choice between “murder innocent civilians” and “target legitimate targets such as the military apparatus that actually murders Palestinians regularly or the right-wing political apparatus that pursues a policy of military hyper-aggressiom, apartheid, and settler colonialism”.
If they chose to do the latter, I doubt nearly as many people would take issue with them, they’d receive vastly more sympathy, and they could finally end the systemic murder and oppression of Palestinians faster.
