What is the definition of my worst enemy? Can I just declare e.g. Putin to be my mortal foe?

If it has to be somebody I have met so far, I will rather save a human than a cat

Why, because a human has more potential to effect the world, has an understanding of death and therefore the worse time dying and in the interest of a species your should allways priotize members of your own species

I have uBlock on my PC, but not on my phone

Body count: pray for death?
