The connection between souls can only exist to the degree of equality with Divinity. That is where they are connected. We are at the end of correction even now, but we need to reveal this level, and that is where we are connected. We cannot connect at the level of this world, it is impossible.

So just bestowing to each other, without an intention to become like the Creator, causes the opposite of what we want, it brings disasters. Baal HaSulam writes that the supposedly good things are those that caused Nazism and Stalin. The ideas are essentially good, it is about the connection of people, unity of everyone, but eventually they cause destruction because they do not connect us to the goal.
