Psychopaths generally like to be alive themselves.

The reason extermination is certain is based upon the fact that perfection is mathematically impossible. So if you allow control they will eventually blow themselves up by miscalculation. It most likely won't end intentionally, but a political miscalculation is all it will take and given enough time, probability of extermination approaches certainty.

A lot of people go and join ISIS, in effect opting in, and people are trying to run into America even illegally, they seem to be opting in too right?

This principle of opting in is about legitimizing the control of government because it is through the consent of the governed that government has any legitimacy at all. However, nothing negates natural law (a concept you seem to be unfamiliar with). If I opt into ISIS, and do harm to another, then indeed because there is a victim, I'm liable for damages and am morally and ethically obligated to make the victim whole. Opting into something doesn't absolve personal responsibility. It in fact increases it.

But when one is forced in, then government cannot even hope to achieve legitimacy. Individual responsibility is therefore negated by the state and people eventually surrender all their rights, don’t know right from wrong, etc. That is a bad situation for government because eventually the corruption that inevitably results will just eat everyone alive. This is because it’s no longer possible to completely confront one’s own actions because they have lost sovereign control.

BTW, the above situation is related to the insanity defense; that one was out of their mind or does not have capacity to control their own actions. If one is not sovereign, then one’s capacity to act is diminished. Without it, full accountability cannot be accomplished and the end result is corruption.

Meh, all this concern about nukes will seem silly after some college student engineers a z virus.

The nuke example is just one of many that I used to show the potential abuse of state power. Take your pick. The only time any violence is excusable is in the interest of self defense. Every time an aggressor initiates violence for control, they not only do wrong, but they demonstrate the bankruptcy of their ideas. This goes for terrorists in all their various forms, whether they wear government costumes or not.
