i think you should say "absolute power" instead of "absolutely power"

To say "I will be grateful" would imply that it is 100% certain that somebody is going to help you. However, at the time of writing those words, you could not be certain that somebody was going to help you. The help was merely hypothetical. Therefore, you should use the conditional tense "would" (to imply possible, hypothetical help) instead of using the modal verb "will" (which implies definite, confirmed help in the future).

Adolf Hitler is considered one of the worst tyrants that who has ever existed in the history, because during his government he killed millions of Jewish people. That was called the Holocaust. butalso he caused In addition, he also caused the Second World War due to his policy interests, because < -- [I don't know what you mean] of  expanding his power in Europe. He was racist, violent and totalitarian.

Adolf Hitler had all the features of an authentic tyrant:   , because  *  he wanted to have achieve absolutely power using by means of injustice, repression and authoritarianism.

* I think you should change the comma to a colon, and delete the word "because".

Although it is grammatically correct, your current sentence does not convey your intended meaning. Think about it: Hitler did not have those features because of what he wanted. Rather, he had those features because he was simply born that way. That was his personality.

Therefore, your intended meaning would be conveyed much better by means of a colon, followed by a list of the characteristics that identify somebody as a tyrant. i.e. "He had all the features of an absolute tyrant: features A, B, and C."

Colons are often used in English sentences before a list.

Hope this helps :)
