Perhaps my perspective is very naive, but here is what my understanding is:
1. Are there good guys and bad guys in this war? Yes, definitely. Ukrainians are the good guys, Russians are the bad guys. And I consider Russians to have a collective responsibility for what is happening because for 20 years they have been largely supporting the autocrat Putin. Sure, if someone asked them today, they'd prefer not to invade Ukraine. The problem is that the majority of Russians, for 20 years, have signalled that they don't want to be asked such questions, they are fine with a dictator who makes these decisions. Only a small minority tried to change that, Putin killed them, the majority still voted for Putin. The average Russian is responsible for Putin, and Putin is the person who decided to start this war.
2. Does this mean that the average Ukrainian soldier is a "good person" and the average Russian soldier is a "bad person"? Definitely not! This would be racist, and logically unreasonable. The average soldier for each side is quite similar to the other side. The Russian soldiers are capable of cruelty and crimes. The Ukrainian soldiers are capable of cruelty are crimes. All wars have cruelty and crimes, because all armies have soldiers capable of cruelty and crimes. The best thing is to NOT start a war.
3. Does this mean that the two sides are equally guilty? Definitely not. Ukrainians did not want to invade Russia. There was no good reason for Russia to start this war.
It is quite simple actually. At least in my mind... Am I wrong?
