Thank you for bringing up the point that Capitalists aren't evil, or that Capitalism should be rejected for moral reasons, I think many people miss that.

But I'm not sure we can talk about a central point in Capital. Capital is a description of a system based on private commodity production, for exchange. It has many points, and one of them is the one you mention about the inevitable replacement of the capitalist mode of production with communism, and it comes at the end of Vol 1. Funnily enough, I believe it's the only point he asserts without arguments, and it's, as we know, thoroughly wrong.

If I had to highlight one important point from Capital, I think Marx's explanation for why the mass poverty of workers is an inescapable necessity for the capitalist mode of production would get my vote (chapters 4, 5, 6 of volume 1). It's an argument he was the first to develop, and that many people still refuse to acknowledge.

You are very right to point out that Capital does indeed predict many phenomena that we see today. In general, Capital holds up as a description of how the capitalist mode of production works.
