Sure a smart villian would be a nice touch, which sure the Sharalayan seem a good fall point given their involvement in quite a number of plot points.

However I doubt we willingly would do anything that catastrophic to lose the people. At best it would have to be outsiders. Which I guess with the current plot is a good example of that possibility.

We are very much above the law. Things curtail to us on a dime regardless of precedents or procedure. If we deem it necessary everything falls in line. I mean even the impact of just having to kill everyone around us was thrown as "that won't be as funny when we forced to kill them all." We just have too much sway everywhere we been.
