I recently finished watching the 3rd season of Game of Thrones (I haven't read the book, I should admit).
One thing does bother me. Ramsay Snow
kept Theon Greyjoy as his prisoner in order to get some information and as a hostage.
But why do we see such terrible tortures? And most of all, why
the castration of the prisoner
that is an irreversible act? Now, it's clear, that the value of the hostage after such procedure decreases very significantly - we can see that
in episode 10, there the father refuses to trade for his son any of the lands.
This is definitely not required to retrieve information - they already had all the information they needed before. Therefore, this procedure is not just cruel, it's also very unprofitable, and can expose serious threats -
I think in season 4 we shall see that, since the sister of Theon marched to his resque.
So, why would Ramsay do that - is he just a psychopath, who tries to satisfy his wicked wishes, despite the cost?
The difference with Lannister Jaimie is that
Jaimie lost only his hand
and this does not give his father very big reasons to start a revenge war.
