Erolz, what if you run a business in the most efficient way and then I come and kill you and burn down whatever you created. Does this means you didn't manage your business well?
Because Makarios didn't manage to stop the crimes of some others that I mention above this doesn't mean he was not a great leader.
This is what Johnson, the president of US said to the Greek ambassador some years before the invasion:
Fuck your parliament and your constitution. America is an elephant. Cyprus is a flea. Greece is a flea. If these two fleas continue itching the elephant, they may just get whacked by the elephant's trunk, whacked good....If your prime minister gives me talk about democracy, parliament and constitutions, he, his parliament and his constitution may not last very long
A great leader, no matter how great, can not transform a flea into an elephant.
He made mistakes, yes, but lets face it: The fate of Cyprus was (and continues to be) very important for some "elephants" to let the leader of a "flea" to form it the way he wanted.
