What is your opinion about Communism?

Only because the US wont let it work. It came close to working in cuba then America started attacking it, its come close to functioning a few times around the world and each and every time it does the US intervenes and install dictators.

So it is unfair to blame the communist system itself, but rather the environment on which it sits.

Or maybe it failed and you want to blame something/someone for that failure.

You're going to ignore how many times Castro was targeted for assassination by CIA? It is said to be "the most" ever, more than 600 attempts. The advancements I mentioned Cuba made on the educational and Healthcare front were all made despite heavy push back from capitalists and blocking every attempt of Cuba to grow and develop. The most deaths Cuba suffered were under the military dictatorship of Batista(guess which country backed him). Things to keep in mind.
