Also no i dont think she knew anything about how she used derek but even if she did to the best of her knowledge Derek killed her mother so i can understand the hate. Actually, we do know the age differences between the two... or more to the point, a rough estimate of the age differences.

According to Derek's driver's license (we see it briefly in S01E11 "Formality" when Kate had him tied up and was torturing him to get Scott's identity), he was born November 7, 1988. Kate's tombstone said she was born in 1983, making her roughly five years older than Derek.

Given that the show starts in 2011, that would make Derek 22-23 and Kate around 28.

Also, knowing that the Hale Arson Conspiracy took place six years previous, that would make Derek 16-17 and Kate around 22 when she seduced and used him to get information as to when everyone would be home.

This would mean that, in accordance with California Penal Code, Kate is guilty of statuatory rape, as Derek was below the California age of consent (18).
