I'm pretty sure I could or would at least attempt to kill someone if they were immediately threatening the life of a someone close to me, or any vulnerable person in my presence(like a young child), and I didn't have time enough to pull off a negotiation or alternative of some sort.
There is a thinking stuff from which all things are made, and which, in its original state, permeates, penetrates, and fills the interspaces of the universe.
Yes, but I couldnt murder someone in cold blood. They would have to do a list of things that are actually in most eyes very easy to cross before I would be fine with doing so. But in the end no, unless they crossed that line....or lines.
