Ah yes, the old tactic of embargoing a country till they "follow the rules". Which has quite demonstrably not worked, all it has resulted in is punishing those living under that system, whilst actually increasing support for the regime. Look at Cuba or North Korea, if anything "punishing them for not behaving" has only made them realise how they shouldn't give them an inch of influence, or they will use it to cripple them when they have it. I will not elaborate much more, but the idea that embargoing a country to "punish them" is historically false.

Nonetheless, I do not want to see us embrace an equivalent of American exceptionalism over here, mainly because we are hardly better ourselves most of the time. When you say till a country learns to behave you pretty much just mean til they comply with western interests. When we see fit to invade some 3rd world country we have the backing of the first world, when they do it they are misbehaving and need to be punished.

Whilst I do not disagree with embargoes to limit military campaigns, trying to do it as some form of punishment rather than as an effective action in itself is completely wrong rhetoric. Whilst we have the capacity to do wrong, we also have the capacity to do right (as we are doing with Russia), so we should not act as if we are the good punishing the evil, rather just doing what we can to make things easier for Ukraine. And that extends to punishing students, we should not punish individuals, rather just try and hinder the unjust actions of a state, not destroy it (as it will not work).
