And you're trying to answer as if you're one who knows.
Yet you don't.
An all knowing, omnipotent god who truly loves his "flock", wouldn't let them destroy each other regardless of time intervals.
Stop trying to justify that which you can't justify.
And yes, we can know how God views things...that is why we have the Bible, to tell us His thoughts on matters...
However, do not let this escape your notice, beloved ones, that one day is with Jehovah as a thousand years and a thousand years as one day. Jehovah is not slow concerning his promise, as some people consider slowness, but he is patient with you because he does not desire anyone to be destroyed but desires all to attain to repentance. 2 Peter 3:8,9
