A world view is built by centuries of diplomacy and mutual interactions. A few people are insignificant as they are not in power long enough.
What diplomacy is there between Ukraine and Russia? I'd say 0.
When it comes to Putin and his views, his whole agenda is based on lies. Lies that it's not a war, but a special operation, lies that Ukraine was part of Russia when in fact current Russia came from Ukraine because Kiev was the capital before Moscow... Putin is acting just like Hitler and Stalin used to. He wants to play big and be remembered in history as a strong leader, but all that people will remember is how many people died in this stupid war.
All things aside, let's say he's 100% right, democracy is bad, gays are bad... Murdering people with other views still makes you a murderer, even if your opinions are better and your way of life is superior. Who gives you the right to tell me how I should live? I'm not a Russian and I don't want to see armed Russians forcing me into submission.
