Countries tending to their own border security isn’t a matter of “good” and “evil.” Russia has far more basis for invading a rapidly arming country on its own border than the US did for invading Iraq or Afghanistan or Vietnam or Korea.
Ukraine's attempts to prepare against invasion do not justify said invasion.
And yes, it's evil, and no, it has nothing to do with their border security, that's a ridiculous suggestion, in the same vein, you would be ok with Russia annexing Poland, Lithuania, Finland or Estonia because they are armed and bordering Russia.
As for the whataboutism, that wasn't the subject.
No, it's ridiculous.
Russian economic development through war doesn't save Russian babies, it will kill them.
