The Tree of Knowedge of Good and Bad/Evil -
It seems to me that at first, human beings followed their natural instincts to survive and reproduce, just like everything under the heavens, which operate according to truth, and do not deviate from their appointed task. So there was no love or hate in their actions.
But the fruit of this tree gives birth to the Will and Desire, so that those who eat it are then able to choose a thing or its opposite, for the good or the bad. This is why it is called ‘The Tree of Knowledge of Good and Evil,’ because da’at in our language refers to will/intention.
