It is not an easy task to get to know Che Guevara and his actions.
Even more than forty years after his death, he is still often mentioned, praised, blamed and criticised in conversations, articles, films or television programmes.
The Cuban media and his faithful admirers have been painting the portrait of a perfect, faultless superhero, while hiding his mistakes and the less popular side of his character (like his rage and his rude outbursts when he was angry and impatient). Meanwhile the (North) American media, the Cuban exiles and his angry enemies introduce him as the Devil himself.
If you want to explore Che by yourself, then you are going to face a difficult task.

You try to read as many biographies of him as possible - in several countries it is still not an easy thing to do as you must order the books from abroad because the biographies or the works of Che are not available anymore (not even in second-hand bookshops) or they haven't even been translated into your language.
The problem with biographies is that they could contain mistakes, inaccuracies, positive or negative prejudices and false information because some of the sources may have a poor memory, or they just simply lie for a reason. Some people want their share of the fifteen-minute-fame in the shadow of the heroic guerrilla or they just want to keep the picture intact - the picture that has been shown to the public for decades.

You also try to obtain and study all his writings, from his diaries to his articles, essays and speeches. And here comes another problem.
Experienced authors like Jon Lee Anderson and Jorge G. Castañeda claim that Che's published diaries have been shortened by his second wife, Aleida March and/or the editor of Centro de Estudios Che Guevara (Che Guevara Studies Centre). For example most of the parts about Chichina (Che's first big love in Argentina) have been deleted from the published version of the Motorcycle Diaries, such as those parts when the young Ernesto wrote about his sexual experiences with girls during his motorcycle journey.
The cut is even more obvious in the book titled Diary Of A Combatant, because the deleted parts (containing sexually explicit remarks or gory descriptions of executions - according to Anderson) are indicated by brackets and in a footnote.

Several sources have claimed that Aleida March was a really jealous woman, she was jealous of everyone who had known Che earlier than her, so it is not a surprise that she removed the parts from his diary where Ernesto wrote about his passionate love for Chichina. Because he was deeply in love with the girl, he had serious plans with her (even marriage), even though later his passion for adventures and journeys took him on a long trip around South America, leaving Chichina behind - who split with him in a letter a few weeks later.
It is also partly understandable - though not really preferable from the point of view of the truth that was so important for Che and that is so important for us, searching for him - that his comments, showing the cruel and cool-blooded combatant who was always ready to kill a traitor while Fidel Castro and other men were just standing and looking away, were deleted.
Just like Fidel Castro, Aleida March wants to preserve the completely pure image of the revolutionary hero, Che Guevara.

If you want to explore the real Che, you must be prepared to read everything about him, no matter if the material casts a good or bad light on him, because a huge part of the material about him has been saturated with a little or more lie or refinement for a long time.
You must be prepared to try to look behind the glamourous picture, to accept that Che was a simple human being with both wonderful and less wonderful characteristic traits.

He was an intelligent, sharp-minded (and tongued) and hard-working man, a passionate leader who wanted to create a better world for everyone, who did sacrifice everything for this dream - but who was also very impatient and demanding for everyone - just as for himself - , whose rage was cruel, who made mistakes just like everyone else, and who wasn't born to be a family man. He was a true revolutionary, a man continuously pushed by dreams and motion, that is why sitting at home with his wife and children - no matter how much he loved them - was not an option for him.
