If god hates sin so much, why did he create us like this, with this traits?
IMHO, every culture deals with this question through their philosophical and religious views. We see ourselves as being separate from animals, and yet we seem to have some of the same desires and faults as animals do. It is interesting that a serpent (an animal) is the antagonist in the Genesis story who conned humans into commiting the original sin. After Adam and Eve eat of the fruit containing the knowledge of good and evil God says that humans are now like God, knowing good from evil. Again, we see the intersection of morality and the human animalistic vessel where each is first separate and then together.
