Communism as a political philosophy is abhorrent and dangerous. It violates the fundamentals of individualism, freedom, and private property rights.
This sounds like you just regurgitated something that you have been told over and over, your entire life.

Communism was not the problem. Corruption was. And is.

This all-or-nothing, either/or, black/white thinking is what gets us into trouble. Not everything about communism is BAD, and not everything about democracy is GOOD. We need to think outside of our respective ideologies and look for what simply WORKS best. And corruption should be our common enemy which unites us instead of dividing us.
