De,
I call into question your assertion "Putin has a murderer's mentality. We know that from his past acts." What are these "acts", specifically. And where is your PROOF. I hope you aren't going to point to, effectively, the same mainstream media and "trusted gubermint" sources you generally decry almost as much as I do?
Now, I don't have any doubt he is WILLING to have people die: can you name a single recent US President, other than maybe Jimmy Carter, who WASN'T willing to have innocents die in the line of carrying out executive duties for some "higher" patriotic ideal?
Trump? He killed plenty of people -- including collateral damage civilians -- while in office. And he was the most peaceable President we've had in decades. And, don't forget he COULD have pardoned Snowden or otherwise have done something to allow Snowden to get the fair, public trial in the US that Snowden has said he would be willing to face. But he didn't.
Biden? Well we know he is okay with rape. And we sure know how enthusiatic he was about killing brown people, even children, in foreign lands.
Hillary? Don't make us both laugh.
Obamba? Have you SEEN the excitement he and Hillary displayed as the watched other people execute Osama? And, I'm sure you know, he okayed widespread use of drones to kill civilians in Iraq and other places. He was even on record in favor of executing US citizens by drone without trial...provided "the government" said they were guilty (without trial).
Bush and Cheney? How many tens of thousands of civilitians, including children, did THEY demonstrate a willinginess...even an enthusiasm ... to kill... Anything for oil and money and power.
Clinton? Well, I reapeat myself.
Bush Senior? Really? The guy who headed the CIA and the multi-generational Bush crime family?
Reagan? Really? How ill informed are you? https://jacobinmag.com/2021/05/greg-grandin-empires-workshop-latin-america
Is Putin willing to kill people? Doubtless -- or I don't think he could have survived the USSR; shut down the Russian mafia which ran things post USSR; fought off US/European Banksters and Empire puppeteers who wanted to make Russia another US vassal state post USSR; etc.
But you seem to have an awful lot of righteous anger on display about Putin, without any real good evidence he is particularly monstrous, by "normal" standards of what passes for "normal government by the people" these days....
