It would be nice to see someone get rid of Putin for high-minded ideals like peace, justice, democracy, or the welfare of Russians & Ukrainians. But I'm not too optimistic on it happening that way.
I worry that anyone w/ the will & the means to assassinate Putin would likely be a power hungry would-be dictator making an aggressive play to replace him. Things could shake out better in the chaos, but they could just as likely go worse
