the command of not eating from the eitz hadaas was only in effect for a really short and waitbale time of only three hours and he was created by hashem's own two hands and was given so much wisdom and knowledge and was really passionate and kind then
why did adam eat from the eitz hadaas?
The answer becomes clear when you realize that the entire intent of the yetzer hora (the evil inclination) is to cause a person to do the opposite of what hashem desires.
All the arguments offered by the yetzer hora to convince a person to transgress a prohibition, or not to perform a mitzvah have one motive: that the person should transgress hashem's will.
There are situations (either because of the individual involved, because of the place, or because of the time) in which doing a mitzvah is specifically important, and in those cases the yetzer hora tries specially to convince us not to do the mitzvah.
Although in truth such mitzvos can be easily kept, since their observance is of great importance, the yetzer hora will present all kinds of demands and rationales with the intent of keeping the person from fulfilling hashem's will.
Certain aspects of the observance of the Torah and its mitzvos should logically be far easier to perform than others. And yet there are times when a person feels that it is actually these “easy” matters which present the greatest challenge. For as explained above, it is precisely with regard to the matters which are most relevant to a person that the yetzer hora presents the greatest challenges.
“With regard to [the observance of] which [mitzvah] was your father more careful?” as meaning that every soul has particular mitzvos which are more connected with its mission on this physical plane than others. since the yetzer hora knows that these mitzvos are of greater importance the yetzer hora then places more obstacles to the fulfilment of those mitzvos.
“Whenever a person is greater than a colleague, his yetzer hora is greater than he is.” For the greater a person is, the more important are the mitzvos he performs. And therefore, the yetzer hora presents him with greater challenges.
On this basis, we can understand why Adam ate from the Tree of Knowledge. Since he was “fashioned by the hands of the Holy One, blessed be He, Himself,” he was “greater than his colleague[s],” and thus “his yetzer hora [was] greater than he.” This is particularly true since the command not to eat from the Tree of Knowledge had far-reaching implications as reflected in the extent of the descent suffered by Adam and all his descendants as a result of his sin. Therefore the yetzer hora, which enclothed itself in the serpent, got adam with all his power.
When G‑d gave the Torah to the Jewish people, He told Moshe: “Say the following to the House of Yaakov.” As our chachomim explain, hashem was telling moshe to give the women the torah first. Why? Our chachomim explain that G‑d wanted to prevent a recurrence of what had happened with the Tree of Knowledge, when Adam, and not Chavah, was the one who heard the command from G‑d.
This had made the aveirah possible. The creation of Chavah the work of hashem's own two hands, as it is written: “And G‑d built the rib….” Nevertheless, since Chavah had not heard the command from G‑d Himself, she erred by increasing the scope of G‑d’s prohibition, stating that it involved not touching the tree as well as not partaking of it. It was her addition which led to the Sin of the Tree of Knowledge.
Had Chavah heard the command not to partake of the fruit of the Tree of Knowledge from G‑d directly, she would not have been fooled by the serpent, and would have kept Adam from sinning, despite all the challenges presented by the yetzer hora, as reflected in our Sages’ statement regarding the giving of the Torah.
