I did say almost. Putin is kind of the extreme example.

If someone is willing to live like an absolute hermit in basically a police state, hiding behind layers and layers of security apparatus, engaging lookalikes and only allowing the loyalty-tested anywhere near him, survival odds improve quite a bit.

But for anyone trying to live anything remotely approaching a normal life, or with any real freedom, your continued survival is completely due to the fact that the overwhelming majority of people in your world have a personal breaker against murder.
