Are you willing to take in 100M russians? Got a big back yard, with schools and hospitals to take care of them? If not, where are they to go exactly? What is it you want them to do? They live in a de-facto dictatorship. Most are normal people trying to just live a life. They have as much effect on Putin as you do (possibly less).
Does that not absolve everyone of everything but Putin himself? His generals were "just following orders", the politicians "couldn't do anything alone", the tank-engineers were "just trying to live a life", the soldiers invading Ukraine "really have no influence", so they choose to murder Ukrainians instead of turning their guns on those they allegedly have no influence over.
$higher_power willing you never end up with a choice of either obeying orders to go kill someone or having your family executed in front of you. Bottom level grunts only have this choice.
