They are all driven by that insatiable will to power, that unappeasable appetite to control and enslave mankind. They are monsters, all of them. Monsters.
As you point out here and in your main article, that will to power is insatiable. I will acknowledge that I have been very naive in my understanding and acceptance of this fact, considering that I am in my early 50s and am just waking up to these realities. I struggled for quite some time trying to understand how any man could have this level of evil desire. I was mistaken in that I assumed that "everyone was like everyone else," in that if I couldn't find it within myself to even comprehend that level of desire for control and power, I couldn't see how anyone else could.
As a more concrete example, since I was a child I could never conceive of how any man could feel comfortable owning another man as a slave, as property. I knew that it had happened very often since the beginning of recorded history, and unfortunately continues to the present. But I guess that I took an ignorant view that led me to believe that it must be more of a societal or cultural ill, i.e., the slave-owners only held slaves since that is what the larger society deemed as lawful/proper. In my ignorance I chose to blame the "larger whole" for the corruption of the individual, rather than assign the blame directly to the individual. Why? I don't know. Perhaps it was just a naive way of avoiding the ugly fact that some men are indeed evil? Maybe it was because I didn't want to believe that it could also be true for me if it was true for others, since I was operating under that mistaken belief that we were indeed "all alike" at the core.
I mistakenly assumed that the primary motivation of the evil I saw around me was purely (material) greed. In my ignorant model it did go a fair distance in explaining the results of what I saw around me. I also mistakenly assumed that their was some finite level for that (material) greed that would eventually be sated, at least enough to stop the drive for total destruction and domination. Perhaps there is for some, or even many? I don't know. But the key point that I have been missing, is that there is another drive, the purely evil lust for domination and control. I am not exactly sure why (since I haven't had enough time to both think it through and more properly educate myself), but my gut sense tells me that this drive is far stronger (than greed for the material) in those that are under its evil spell, and that it is one that is less easily (if ever) sated by incremental gain. It appears to be the one that is totally insatiable in the worst cases of afflication.
