I suppose It's really a people problem more than a system problem though. :/

No, it's a system problem. The worst abuses of power under communist regimes pale in comparison to the atrocities capitalist powers commit on a regular basis. Even if you took the Black Book of Communism at face value and assumed every bad thing that happened in the USSR or the PRC was the direct, intended result of the government it would not hold a candle to the British rule of India, the European colonization of the Americas, or the austerity-driven debt slavery of the global south under neocolonialism.

A few government officials taking bribes is not morally or logistically comparable to systematic chattel slavery or stealing the surplus labor value of billions.
