LOL, you're ridiculous. If Putin invading neighboring Ukraine for territorial annexation is not the actions of a psychopathic dictator, what is? Ask Finland, why they didn't trust their treaties with Russia and were suddenly desperate to join NATO.
Many countries are corrupt, including Russia, does that mean we should invade Russia?
Blaming Ukraine for casualties that happen in its defense from Putin's invasion is moronic. Its like blaming the police for an accidental shooting in a bank robbery.
Putin invaded Ukraine for specific purposes.
He doesn’t want or need the additional territory.
