There is a large problem with this philosophy.

Not all lives are equal.
We kill millions of bacteria so that we can survive. (much without our evening knowing it)
We kill all kinds of plants and animals so that we can eat.

We kill people who are trying to kill us. (self defense)

Because of RBG, we have killed millions of pre-children.
(how many women's lives have we saved? a very unknown number)

In the future we will recognize evil. We will recognize psychopaths, and we will remove them from our lives.

Thoughts create. Evil begets evil.

Sooooo, many planets / races have decided to kill (or electrically erase their minds) any psychopaths that come to their attention.

Can we stay on the pinnacle of life philosophy and state that all life is sacred?
At what point is it more important to protect ourselves, our future and our planet?
