No, it's much worse. Collective Punishment is a globally-recognized war crime:

The US and the EU are flagrantly violating the Geneva Convention and everyone I know is cheering it on. Absolutely sickening.
It seems any/many actions taken against an adversary will have knock-on effects of the population of the adversary, whether financial/economic or militaristic.
Does the focused nature of the sanctions thus far not change your calculus? Or is it SWIFT only that you're referring to? What about: banning private Russian flights from air space throughout Europe; FedEx refusing to make deliveries to Russia; Arming Ukraine to enable a quagmire, costing the Russian government several billions per day to sustain their effort, and harming their economic position; even broad and impactful tariffs could be seen as a Collective Punishment?
I'm having a hard time determining what actions are not a violation of the Collective Punishment ban under your generous interpretation, short of direct military conflict. I don't think incentivizing hot war was the intention of those rules. My understanding was that they are meant to apply to POWs and noncombatants under rule of a warring party.
What's your alternative to sanctions? Do nothing? Move NATO troops into Ukraine and start WWIII?

which is up for debate in this instance. I don't agree with you.
I do think the literal bombing of residences and hospitals, false flag operations, wearing the enemy's uniform, etc. etc. all constitute provable warcrimes which should be investigated. Not that I want to devolve into whataboutism, which I realize I'm skirting close to.
It's not up for debate. The Russian army acts on behalf of Russia. Therefore the whole of Russia is collectively responsible for the actions of the Russian army.
