You're mishmashing shit tougher with no logical process to it , only to play the devil's advocate.
Bad shit happens all the time. And this argument literally has nothing to do with equality. A pilot losing control of a plane and his passengers all die. It's a terrible thing to happen. But that isn't linked to equality .it's simply fate. No one can do anything about it.
Communism in its cultural aspect is the antithesis of equality. it's a collectivist ideology that seeks to eradicate all diffrence.
Unregulated capitalism is destined to become a corporation monopoly. it's less the fault of man and more of a crertian outcome 1+1=2.
That last part is what I would agree with. people hurt people because they been taught a lie called equality. And when they grow up to find it's nothing but facade and illusions. Down to the very core of biology. They'll have no choice but to accept suffering and depression...or lash out and make their own worth.
What I would teach instead of equality will be mercy. Because equality is nice in theory but that is all it'll ever be. A theory that's never practical. But mercy transcends that. it's like a divine morality that embodies true righteousness.
