The problem is that if you go with option 1 to begin with, you'll never ever get option 2 at all. And if that's the case, you might as well kill all of mankind preemptively to save everyone the pain and the misery.
Anyway, that we haven't evolved at all during the last 2000 years is grossly inaccurate to say the least, even if we still are by and large a bunch of hateful, violent rat bastards.
