There are people there who deserve everything they get, and there are people there who are getting caught up in this. It's the same in basically every country, there are going to be good people, awful people, people who just want to keep their heads down and stay out of this shit, etc.
The main thing that makes the sanctions unfortunate is that, while even the strongest authoritarian still needs some amount of people who can enable their regime, the moral weight of executive decisions still falls more on those making the decisions, and they're still going to suffer far less from sanctions than the people underneath them. Even if there are common people out there who have played a part in everything leading up to this mess, they'll suffer far less than the oligarchs and others who're responsible for wiedling the power they've been given.
But that's war in a nutshell, to be honest. No matter how just it is, whether it be through bombs and invasion or sanctions and embargoes, even when it catches the right people in the crossfire the impact is going to be disproportionately weighted towards those whose individual part in the mess they've created is the smallest, while those who've profited the most from the evil they've created rarely suffer anything resembling justice for it.
Not to mention, in war someone's going to suffer for it. One can feel pity for some Russian conscripts being led into a meat-grinder, even as one acknowledges that in in war someone dies either way, and better it be those of the aggressor than that of one who's in the battlefield because their home and family are at stake.
So too can one also still regret that things have to end this way for those conscripts who are actually in over their heads, while still regarding the war criminals and their enablers with the contempt they deserve. The unfortunate reality is, no matter how sympathetic any individual soldier on the aggressor's side may be, no matter how big or small their part in this atrocity is, their lives are being spent all the same, and it still ends up boiling down to a Russian soldier's life vs. the life of whoever they end up against on the battlefield.
As this is the DF forum, "it was inevitable" would be fitting here.
