When evil no longer needs or wants to hide, when it fills the world with lies and stupity ( men with dicks can be women, miltary leaders openly betray the country and dont care who knows).
This means one of two things,
1/ Evil is so strong it will openly try to crush all around it, kill endlesly and say its good, fill the world with hate.
2/ Evil is losing and in fear, it will do everything it can to "salt the earth" to distroy all it can reach. Better that everything burns so that rebuilding will be near to impossible.
So whos fault is this, the answer is good, yes good wants to understand, good wanted to help, good said "give them more freedom they will understand to be good". The greatest supporter of evil is good, it gives evil all the freedom it needs.(WWII could of been stopped or greatly limited but good said, no evil will stop if we give evil what it wants )
With out good evil would be powerless, with good evil does what it wants. Which is more evil, evil or that which lets evil do as it wants ?
