We can look at the history of Russia and point to all the bad it entails, which is all true, but we also have consider the here and now, as well the future; which is ultimately in the hands of the global community. As it currently exists, Russia really isn't good at anything beyond exporting energy and to a much lesser extant raw materials. Truth be told, they are completely dependent on the energy needs of the world in order for their current system to even work as badly as it does. Without break thrus and investment in energy alternatives, we will continue to be at the peril of regimes like Russia, Venezuela, and many different bad actors in the Middle East (who are also overly dependent upon energy exportation), At the end of the day, energy independence isn't just critical for the United States, to be honest, it's critical for all the world's nations, as it provides a layer of stability and prevents bad actors to having access to as much wealth as they do now. Whether each of us like it or not, whenever each of us fills up at the pump, or heats our houses, etc, we are all helping to prop up these sorts of regimes. None of us would choose to do this, but at current, there aren't enough practical options available for us to choose not only on our own, but also collectively.
You can add in the need for all this in an overall climate perspective, but I actually think the more pressing issue at the moment is to limit these sorts of bad actors from a seemingly unlimited piggy bank. That isn't to say that the climate aspect of this isn't critical, it is to me, but right now that seems like sauce for the goose. I do believe we are making headway on all this, and as it ultimately relates to the Russian people, the reality is, no matter the outcome of this conflict, the days of this model of "government" are numbered because eventually, like many other countries, they will find themselves without a chair when the music stops (relax Oil and Gas folks, it won't stop entirely, but change and slow).
